Description

The present invention provides a device for keeping constant

the

temperature of beer kegs.

  Indeed, currently the barrels are stored on the ground and undergoes the

  temperature variations in the storage room.

  Variations in the temperature of the storage room results in a loss of the quantity of beer dispensed. The device according to the invention makes it possible to

remedy this drawback.

  According to a first characteristic, it has a parallelepipedal box comprising on the front face, three access doors, as well as the regulation drawer. The upper part has three half-covers

sliding and removable.

  The box to keep the temperature constant, consists of elements made of electro-galvanized and painted sheet steel (powder paint

exterior quality).

  The base of the box consists of a panel of marine plywood, comprising at its bottom two U-shaped housings, fitted with feet

adjustment by screw.

  The internal part is coated with a stainless steel sheet, serving at the same time: * of housing for the regulation drawer, * for the support of a barrel of small quantity,

  * and for ease of sliding for the placement of barrels.

  Maintaining at constant temperature is achieved using the regulation drawer.

  This includes a compressor, a condenser, an evaporator, a

  dehydrator, resistance and tangential turbine.

  On the front of the regulating drawer, there are two grids for the air inlet and outlet. In the center is the electric control, the temperature indicator

and the operation indicator.

  The accompanying drawings illustrate the invention; Figure 1 shows the box seen from above without its covers. The outer casing reference 1 is made of galvanized sheet metal with a thickness of 15/10 mm as well as the

  bottom mark 2 and the 3 doors mark 3.

  The folds made with reference 6 on the envelope with reference 1, are used to maintain

insulation mark 4.

  The insulation of the reference base 4A is both maintained by the insulation reference 4 and by the cleats in sheet metal reference 1. These being fixed on the frames

mark 5.

  The rear bottom mark 2 is produced by folding, it is fixed by screwing mark 10.

  The folds made with reference 6 serve to maintain the insulation with reference 8.

  1 The reference doors 3 are made by folding. The folds mark 6 are used to maintain the insulator mark 4 The artlculatlon of the doors is carried out using 2 hinges mark 7 fixed on self-drilling screws. A pivoting reference handle 7 is used to open and maintain it in the closed position. A rectangular frame 5 of rectangular shape made of 40 mm square tube, serves at the same time as a stiffener, to hold sheets 1 and 2, of articulation and point

closing doors.

  Figure 2 shows the front view without the doors. The bottom of the reference box 1 is made of marine plywood 25 mm thick. It is provided at its lower part, with two U-shaped frame rails 2 on

  which are fixed 6 feet of adjustment.

  On its upper part, it is covered with a stainless steel sheet item 4 covering the bottom. This sheet is used both for maintaining the insulation in the lower part, item 5, for supporting the small capacity drum item 6, for housing the control drawer item 7. This sheet being made in one piece, is used for both protecting the bottom and sealing the whole. In the central part, air intake openings reference 11 are cut opposite those of the regulation drawer. In item 12, there is a chimney of rectangular section which fits into the air outlet of the regulation drawer. On the upper part of the chimney, there is a deflector allowing to distribute the air flow. On the envelope mark 1, are made folds mark 7 which are used for fixing by screwing on the bottom in cortre-plated mark 1 At the upper part, there are 2 pieces of reference 8 made of aluminum, serving both to hold and seal the insulation in its upper part and as slides for the fixed covers.

  and mobile. They will be fixed by self-drilling screws.

  Figure 3 shows the 3 movable covers and the fixed cover View of

  above the cover, mark 1, made of sheet metal, same as the envelope.

  The fold mark 2 and the U welded, are used to maintain the insulation. In the central part, two U-shaped plates are used as stiffeners. The cover is fixed with self-drilling screws on the aluminum guides, item 8 in Figure 2. The movable covers will be made in the same

  material as the main envelope.

  Each cover has folds mark 6 used to maintain the insulation mark 7. They also have an opening mark 8 allowing the passage of pipes

gas and beer supply.

  1 On the front part, they will be fitted with an aluminum strip used both for sealing the insulation and for easier handling. The regulation drawer, Figure 4 is made of sheet steel with a thickness of 2 mm. It has in its rear part, a stainless steel sheetJdable item 1 serving at the same time, as support for the evaporator item 2 and evaporation tank item 3. The evaporator item 4 is of the contardo type with a power of 580 watts at T 100 C; It is equipped with a tangential turbine reference 5 of 270 mm long and 60 mm in diameter with a flow of 230 m3 / h and a resistance reference 7 with a power of 250 watts. Reference 6 represents the air outlet chimney, reference 7 represents the air intake vents. The entire rear part is fully insulated. In the front part of the drawer is a hermetic compressor item 8 of 1/4 CV and 678 watts of cooling power + 45 C

of condensation.

  The reference 9 represents the condenser of the contardo type with a power of 860 watts at T 15 C. The assembly being charged in freon of the type 404 A. On the front face of the drawer, between the air circulation grilles, find the combined power supply with light switch, thermostat and

temperature indicator.

  FIG. 5 represents the top view of the regulation drawer, the reference 6 represents the air outlet opening. The mark 7 represents the air intake vents, In the front part of the drawer is a compressor

  item 8, as well as a condenser item 9.

  As an example, the parallelepiped box will have dimensions of

  around 1800 mm long, 950 mm high and 800 mm deep.

  The device according to the invention is particularly intended for keeping beer kegs at constant temperature in drinking establishments
