Chapter 3 Description and Technical Data Page 12 Performance Description

3 Description and Technical Data

3.1 Performance Description

Banquet trolleys are intended for hygienic transportation of food in the food service industry and large-scale catering establishments. Their main function is to transport for short distances and to keep food warm. They hold up prepared meals in gastronorm containers or already portioned and covered meals on grids.

The unheated banquet trolley BKW1/23 L-GN is designed for transport of gastronorm containers, gastronorm grids and prepared trays with warm or cold meals for short distances.

Heated banquet trolleys are designed to keep food warm and to transport hot food in gastronorm containers or portioned meals.

The models BKW1/14 L-GN+5PK and BKW1/28 B-GN+10PK include an additional insulated compartment that can be used together with a cold storage plate as a cooling compartment. So you can transport either warm or chilled meals simultaneously.

3.2 Intended Use

Banquet trolleys are only intended to hold up gastronorm containers with prepared food or already portioned meals on grids. They transport prepared food already portioned on crockery items ready for serving in the food service industry and large-scale catering establishments.

The intended use means the predetermined procedures, compliance with the indicated specifications and use of the delivered or additionally available original accessories.

Any other use of the appliance is considered as unintended use.

3.3 Improper Use

Any other use, especially loading of the banquet trolley with the other loads as given, is not permitted. It is not permitted to cook food. Transport of living beings, heavy and sharp-edged items, loose crockery items or stacks of crockery items is

not permitted. Banquet trolleys are not intended to be used as a seating surface or as a storing surface for items. In no

case may people sit down or stand on or in to the appliance. The manufacturer and suppliers are not liable for any consequential damages resulting from an unintended

use. No liability is assumed and no warranty claims can be submitted for damages caused by improper use.

3.4.4 Appliance description

The banquet trolley is made of stainless steel and its surface is polished. The appliance is equipped with a door on the front side. The removable support ledge frames are fitted on the sides in the interior of the appliance to put the Gastronorm containers and/or grids. The banquet trolley is equipped with two fixed and two lockable swivel casters with total brakes. The banquet trolley is suitable for transport over carpets owing to a particular size of casters fitted with special tyres. The double-walled folding door is a thermal and sound insulation and you can swing it to an angle of 270° and lock. Two circumferential protective strips protect the appliance against damages when moving and transporting it. The push bars of all the banquet trolleys (except BKW1/36 B-GN and BKW1/28 B-GN+10PK) move backwards with respect to the outer contour. This protects fingers sufficiently when holding the handles between impact protection and push bars in such a way that there is no risk of injury when hitting, for instance, rough walls.

The neutral banquet trolley BKW1/23 L-GN does not have a heating device. Heated banquet trolleys (BKW1/14 L-GN, BKW1/20 L-GN and BKW1/36 B-GN) are equipped with a heating

unit with a circulating air blower and a water tank This generates a uniform circulating stream of moist hot air in the interior of the trolley that prevents food from drying out. Water in the water tank (700 ml) is sufficient for approx. 3,5 operating hours. The operating temperature is to be set continuously by means of a rotary thermostat between 30 ℃ and 95 ℃. The temperature will be displayed on the display arranged on the door of the banquet trolley. The circulating air blower runs independently of the heating during the complete operation.

The models BKW1/14 L-GN+5PK and BKW1/28 B-GN+10PK are equipped with an additional insulated compartment above the heat area. This compartment can be equipped additionally with a cold storage plate to be able to keep the temperature constant in the interior of the compartment for approx. 4 hours at approx. 4℃ when the ambient temperature is approx. 25°C.

If it is intended to transport the banquet trolley by lorry, a transport securing device available at HUPFER can be used. This additional option must be indicated when ordering. It is possible to fasten the appliance without causing any damages and transport it safely by lorry due to the safety holders and reinforced side walls of the banquet trolley.

7.4 Special Care Instructions

The resistance to corrosion of stainless steels is based on a passive layer which is formed on the surface when oxygen is admitted. The oxygen in the air is sufficient for the formation of the passive layer, so that faults or damage to the passive layer can be remedied agai n automatically by mechanical action.

The passive layer develops or reforms more quickly when the steel comes into contact with flowing water containing oxygen. The passive layer can be chemically damaged or disrupted by agents having a reducing (oxygen-consuming) action when the steel comes into contact with them in concentrated form or at high temperatures.

Such aggressive substances are for example:

 substances containing salt and sulphur  chlorides (salts)  seasoning concentrates (e.g. mustard, vinegar essence, seasoning cubes, saline solutions)

Further damages can occur due to:

 extraneous rust (e.g. from other components, tools or rust film)  iron particles (e.g. grinding dust)  contact with non-ferrous metals (element formation)  lack of oxygen (e.g. no admission of air, low-oxygen water).

General working principles for the handling of appliances made of "refined stainless steel":

 Always keep the surface of appliances made from stainless steel clean and accessible to the air.  Use cleaning agents suitable for stainless steel. No bleaching and chloride-containing cleaning

agents should be used.

 Remove layers of lime scale, grease, starch and egg-white daily by cleaning. Corrosion can occur

underneath these layers due to lack of air admission.

 After each cleaning operation remove all cleaning agent residues by wiping thoroughly. Afterwards,

the surface should be thoroughly dried.

 Do not bring parts made from stainless steel into contact with concentrated acids, seasonings, salts

etc. for longer than is absolutely necessary. Acid fumes which generate during cleaning of tiles also promote the corrosion of "refined stainless steel".

Cleaning and Care Chapter 7

Special Care Instructions Page 27

 Avoid damaging the surface of the stainless steel, particularly by metals other than stainless steel.  Residues of extraneous metals produce extremely small amounts of chemical elements which can

cause corrosion. In any case, contact with iron and steel should be avoided because that leads to extraneous rust. If stainless steel comes into contact with iron (steel wool, steel particles from pipes, water containing iron), this can be a trigger for corrosion. Therefore, for mechanical cleaning use exclusively refined steel wool or brushes with natural, plastics or refined steel bristles. Steel wool or brushes with unalloyed steel lead to extraneous rust due to abrasion.
