The front dishwasher

The front -mounted dishwasher is the closest to the domestic dishwasher. Indeed, it is presented in the same way, with a door on the front. This dishwasher can be installed on the floor, under a plunge with a special fitting. It can also be placed in height up to 120 cm for a better comfort of use or to be above the drain network of the water and do not need a pump of drainage.

This model is generally suitable for small and medium catering , which serves between 40 and 120 covers a day.

The hood dishwasher

This one is more suited to the average and the great catering , which serves every day from 100 to 300 covers . It can be combined with an input table and an output table for prewashing, filling baskets, drying the dishes and emptying the baskets. These tables are often made of stainless steel , and sometimes tailor-made to fit perfectly to the space of your kitchen. The dishwasher and the two tables are assembled together by a hooking system.

This type of machine offers better performance than the front-opening dishwasher. It is faster and more comfortable to use thanks to its sliding systems between the washing area and the inlet and outlet tables.

What factors to consider when choosing a professional dishwasher?

To choose a suitable device, it must first assess its needs in terms of performance: front for small kitchens, midsize kitchens may opt for a frontal machine or hood , and kitchens should rather be directed towards the hood dishwashers or automatic advancement .

Finally, there are a few criteria to consider when choosing between different models:

  • The presence of a double wall reduces the heat loss, and also the noise.
  • Some machines make it possible to save water thanks to an intelligent filling system .

Freezer Comparison and Buying Guide

Monday, 13 February 2017 14:04:42 Europe/London

In general, the choice of freezer is based on two main criteria: the area available in your kitchen and the number of people who use it. It is only after you have determined these two elements that you are going to talk about options. Moreover, it is difficult to say that one product is better than another, because each freezer has its specificity, especially since manufacturers are increasingly innovating in the design of this appliance. If you require futher help or information about commercial freezers, do not hesitate to contact us or view our shop.

The main selection criteria

The available space in your kitchen

The freezer is essential in your kitchen to keep your food. To invest in this product, it is necessary to define in advance the important points to be taken into account. Indeed, the first criterion of selection concerns the surface dedicated to the freezer in your home. You will therefore focus your attention on the dimensions of your future freezer. If you have limited space, a space saving freezer will do the trick, as it occupies only a few centimeters. In this case, the imposing models are to be banished. On the other hand, if you have enough room to accommodate a large item, the size of the freezer will not cause you any problems. In fact, the dimension criterion will avoid unpleasant surprises in the installation of your freezer.

The capacity of the freezer

The second choice criterion refers to the number of users. How many mouths should be fed? To do this, you should check the capacity of the device. However, it is recommended to opt for a freezer under 250L for a household of one to 3 people. Beyond this capacity, they are models dedicated to large families. Otherwise, very large freezers of 500L or more are used for heavy use. You might find these types of Freezer in the fish shops or in the kitchen of a restaurant.

Other considerations

Energy consumption

Given that the freezer is an electrical appliance, that is, which operates through electricity, energy consumption will be the next essential point to consider. It goes from class A +++, the most economical to class G, the most greedy. Users tend to look for the most economical way to reduce their electricity bills.

Moreover, the freezer is connected continuously, which requires a high energy. Some brands of freezers are considered to be more economical than others. Note that the A + class saves you 22% energy, A + + 44% and A + + + 66%. It is true that these devices are more expensive than those of class A, but on top of that, you would participate in an ecological effort for the planet.

Not only is your freezer economical, but it is also environmentally friendly. So do not hesitate to buy a slightly more expensive device that will save you money afterwards.

The new features

Appliance manufacturers have equipped new features in freezers, making choosing more difficult . In other words, we are witnessing a real technical innovation with the new generation freezers. These options are essentially aimed at making the use of this appliance more comfortable and practical. Among these revolutionary options are:

    Automatic gel:

this is an automatic ice making. It is a fast freezing system allowing a very large quantity of fresh products to freeze quickly.

    The "EasyOpening" system :

this function confers an easy opening by means of depressurization channel. In this way, it is easier to open the door.

    The Led display:

Many Freezer have this technology. Light-emitting diodes are often dedicated to control or even adjustment. In other words, this function is presented as a control screen not only to monitor temperatures but also to easily adjust them.

    The "Spacewise" option:

it is a new system of storage baskets. It provides an optimized organization of your food with better accessibility. It should be noted that this system does not use drawers.

    Super insulation:

this function consists in isolating as far as possible the frozen products stored in the freezer, in order to keep them in cool.

Different types of freezer

There are several kinds of freezer although the freezer cabinet and chest freezer are the best known.

    The freezer cabinet

The freezer wardrobe is no longer to present, as it is the most widespread these days. Most of the time, it is paired with a refrigerator one door. This type of freezer is available in several sizes. It usually includes drawers or lockers to store food. In its location, it occupies only a minimal place on the ground. This makes it easy to integrate into the kitchen.

    The chest freezer

The chest freezer which is characterized by its opening from the top. The main advantage of this article is that the products are more accessible because you do not have to kneel to take them. Indeed, it is bulky, but it allows to store in large quantity the food. It is most often baskets to compartmentalize the distribution of food.

    Under counter freezers

The under counter freezer is intended for the storage of small quantities of foodstuffs such as small bottles and cans. This is another type of small cabinet freezer as it opens to the side. It can also incorporate an outdoor kitchen or an office.

    The built-in freezer

The built-in freezer or freezer room is inserted into a kitchen cabinet, it is also called a freezer cupboard. Also called an integrable freezer, as it was designed to be placed as part of the kitchen. In this context, its door is identical to that of the furniture of the kitchen.

Refrigeration systems used in freezers

Freezers do not all cool in the same way. Moreover, the cooling systems are divided into 3 modes including static cooling, cold SmartFrost and NoFrost ventilated cooling.

Static cold: with this system, the cold spreads naturally. It is therefore important to think about classifying commodities according to the different temperature levels. This type of cooling offers high freezing and high quality insulation without generating additional energy consumption. However, defrosting must be done manually and regularly to prevent frost deposits in the unit. The only way to save money with a freezer in the static cooling system is to maintain it.

The SmartFrost cold: this system is also called cold StopFrost. It works exactly the same way as static cold, except that it guarantees up to 80% less frost. This means fewer de-icing problems, but also lower electricity bills. Generally, cabinet freezers are equipped with the SmartFrost system and StopFrost chest freezers.

Ventilated cooling: it is better known as the NoFrost system. It produces the same temperature throughout the freezer. Therefore, you do not have to store foods according to temperature levels. The major advantage of the NoFrost system is that it creates no frost. However, this type of cold does not exist in chest freezers.

The advantage of using the freezer

The commercial freezer is a very important material in the professional kitchen because you can store all kinds of food. Moreover, its refrigeration system aims to keep the foods fresh, even over a very long time. In the event of a power failure, the freezer has a sufficiently long battery life to avoid defrosting the products. As you are a helpful help, think about taking care of it .

How to maintain your freezer?

As an appliance, servicing the freezer plays a role in its proper functioning. On the other hand, a lack of maintenance can lead to a bad odor and taste on food. Let us also remember that the cold that it generates does not kill the bacteria, it neutralizes them only. As a result, a little cleaning is required. You do not have to do it every month, 2 to 3 times a year is ample enough. To do this, clean the inside with a sponge soaked in a product such as white vinegar. Pass on all corners, namely, grills, seals and bins. Then rinse with a clean, dry cloth. Otherwise, for the maintenance of the exterior, use a washerwasher. The most delicate part is the ventilation grille behind, be very careful when dusting.

Which knife for what: The best blade for every purpose - Part 1

Friday, 10 February 2017 12:01:52 Europe/London

As different as the material to be cut can be, then knives can also different. So that you are perfectly equipped for any cutting work in the kitchen, there is an optimal knife for every application, which differs in size, blade shape and cutting edge from others. We guide you through the selection of different types of knives from our online shop, which are part of both the basic and the professional kitchen equipment, and thus give you an overview of the correct use.

Various knives for fruit and vegetables

Special vegetable knives have a short, pointed blade and are also suitable for cutting fruit. Thanks to the straight blade, you can not just clean the food, but also cut it into small pieces or even use the knife to decorate the dishes.

Commercial Fridge Buying Guide

Wednesday, 8 February 2017 11:25:25 Europe/London

A kitchen without a refrigerator is unthinkable. This applies to private households, but even more to catering. However, the stricter rules on the hygiene and storage of foodstuffs require special equipment,a commercial kitchen fridge. What really matters with a refrigerator for the catering trade, this article aims shows somewhat more precisely.

What size fridge should I buy?

A general assessment of the size of the respective refrigerator can not be made. The physical size will depend on the size of the area you wish to store the fridge in. The capacity depends on the food held and the daily number of guests. Nevertheless, it should be appreciated that it is too large or too small. If the food is kept too tight, the energy consumption of the refrigerator increases. Of course, also consider:

      • + the annual electricity consumption and
      • + energy efficiency class

In addition, the food can be damaged by the close storage. A refrigeration unit with a capacity of 141 liters is mainly suitable for small snack stands and restaurants, where the fewest items have to be stored longer than a few hours. In large-scale catering, refrigerators with a capacity of more than 1,000 liters are estimated. The appliances often have a cooling air circulating system that simplifies the storage of food.

Before buying a refrigerator for restaurants you should therefore consider the following:

  • + Amount of food to be stored
  • + Estimated storage time
  • + type of food
  • + Is the food already prepared

Energy Efficiency Explained

Unlike washing machines , dishwashers or dryers no "standard operation" to measure the energy consumption is necessary for refrigerators because the refrigerator over the whole year in operation. In this respect, the description of the values ??on the EU product data sheet is simplified.

The key parameters are explained below:

Energy Efficiency

At this value resulting from the technological progress constantly changes. The classification is based not only on the electricity consumption, but also on the size (ie the net capacity, expressed in liters). It may well be that a refrigerator with an annual electricity consumption of 120 kWh is in a better energy efficiency class than one with only 90 kWh. The ratio of the two values ??to one another is decisive.

Note: A refrigerator in the residue class A +++ saves against an A + device average 50 percent energy. An A ++ appliance saves nevertheless still 25 percent less energy than an A + device. The higher purchase price for a more efficient device class is therefore worthwhile after a certain number of operating hours.

Annual electricity consumption

This is expressed in kilowatt hours and must always be seen in relation to the size of the device. However, the fact that this value plays an important role for the user of the refrigerator is also clear: the refrigerator is the only large electrical appliance in a kitchen that is permanently switched on all year round. It would be quite surprising if the annual electricity consumption were not shown separately on the energy label.

Hygiene Considerations

Already pre-prepared food stuff can simply stored in the refrigerator and usually takes up more storage space, however they can not be easily stored together with fresh food. So seperate shelves and storeage conpartmens is essential. If a gastronomy operation uses a lot of fresh fruit and vegetables, the refrigerator should have additional compartments for storage. This is useful for hygienic reasons, as the compartments allow separation.

It is also important that restaurateurs are aware that professional refrigerators often do not have an integrated freezer compartment. As a rule, a freezer must be provided in addition to the refrigerator. This must, of course, guarantee compliance with the cold chain at all times.

Costs

What are the cost of a gastronomic refrigerator depends on various factors:

  • Size
  • Cooling variant
  • Design
  • Brand

A simple bottle refrigerator with a stainless steel case and a glass door is quite already available at a price as little as £350 for a Polar model. Refrigerated display cabinets, which are suitable for the display of finished food and have a decorative purpose, are more expensive. From around £400 restaurateurs have to start here, the size of the refrigerator and the shape of course make a difference. Simple display cabinets with a stainless steel base and a glass cover are cheaper than similar models, which already have cooling air circulation.

If the refrigerator serves the storage of food directly in the kitchen area, the optics plays only a subordinate role. Here it is more important that the device occupies as little space as possible, but offers sufficient space. Smaller devices such as undercounter fridges and smaller upright fridges are already available for less than £1000 without having to deal with any disadvantages. The temperature can easily be set in a range between minus 2 degrees and plus 8 degrees Celsius, while a thermometer integrated in the case displays the temperature continuously. Cooling is also integrated in the units.

Kitchens that need a larger capacity of 1,000 and more liters are more expensive to buy. The units usually have two doors and have a sufficient depth to accommodate boxes. It is especially useful in establishments which receive fresh meat directly from the butcher and have to refrigerate it before preparation, such refrigerators are ideal. However, they have their price. At least £1500 must be spent on such equipment. Foster cabinet fridges offer a great choice for storage size, useability and a competitive price for your professional kitchen.

How does a refrigerator actually work?

The functional principle of a refrigerator can be made clear with one sentence:

  • A refrigerator removes the heat in its interior and directs it into the environment.

Just: how does he do that? To understand this, we pursue once - similar to the dryers with heat pump - the way of the refrigerant without our refrigerator can not do:

The refrigerant

The refrigerant is a special fluid whose boiling point at about -30 ° C is. This boiling point is therefore considerably below the temperature of the food in the refrigerator. The refrigerant is exposed to heat in the interior of the refrigerator, thereby evaporating and thereby reducing the heat.

As refrigerant used today isobutane in the field of refrigerators and air conditioners under the name R-600a is used. R-600a has the advantage of a very low greenhouse effect, but is combustible and is therefore passed on to the inside rear wall of the refrigerator in the cooling compartment.

The evaporator

In the cold room (specifically in the back wall of the refrigerator compartment), there is a coil, called evaporator , in which the refrigerant of the heat of the inner space is exposed. Because of its extremely low boiling point evaporates here, the refrigerant and then flows as a gas continues to compressor.

This is actually the decisive point in the refrigeration chain: the evaporative heat of the refrigerant is precisely that heat which is withdrawn from the food in the interior of the refrigerator. There has thus become colder, and the vaporized coolant must now to be re-used in any way to its original liquid state are placed.

The compressor and the condenser

The re-liquefaction of the refrigerant is achieved with a trick: the compressor , the internal pressure of the now gaseous refrigerant is simply increased, and indeed so far that the condensation and boiling point moves in the vicinity of the normal room temperature. In capacitor (exposed to the normal room temperature) now condenses the gaseous refrigerant, will once again liquid and is at this change of its aggregate state heat to its surroundings (maybe one or two still recalls the conservation of energy from his school days: energy goes Never lost, but is always transformed into another form).

The thus recovered cooling liquid can now be fed back into the tube system in the interior of the refrigerator.
