DE2346339A1 - Pneumatic cheese fragments press - applying vacuum below diaphragm resting on followers of cheese moulds inside sealed box - Google Patents

Abstract

A pneumatic press for cheese fragments, which a content of residual whey, consists of a box with inclined bottom, discharging into a whey collector tank below it. The moulds are assembled in the box and their followers, shaped like a truncated cone, are in contact with the diaphragm which covers the box. This is much simpler than a pneumatic or hydraulic piston actuator requiring cylinders and push rods. It combines a max. prodn. capacity with a min. of time required.

Zuidvliet 402, Leeuwarde :.

Device for the pneumatic pressing of between a mold bottom and a Cheese curd still containing residual whey, which is located on the walls of the mold and strokes along the mold walls.

The invention relates to a device for pneumatically pressing itself between a mold bottom and one on the mold walls Cheese curd still containing residual whey located along the sweeping follower, with the shape in one at the top by a flexible Membrane covered box is arranged, which box with a Connection piece for a vacuum line and a whey discharge is provided.

Such a device is known. The pressing takes place through Impacts acting on the follower, which are connected to the piston of a pneumatic or hydraulic piston-cylinder system via a rod are.

The purpose of the invention is to avoid this intricate mechanism.

For this purpose, the device according to the invention is designed such that in the box with a sloping bottom with the whey collecting container underneath, a number of molds are arranged, all of which have poles at the same time are in contact with the membrane covering the box.

In that all followers are in contact with the membrane at the same time a large capacity is achieved with minimal expenditure of time.

The device can be designed in such a way that the cheese molds are round and are arranged touching each other in the rectangular box, with the membrane provided with a stretched edge between the upper edge of the box with support flange and one detachable the box attachable frame is clamped.

After the cheese molds filled with curd and the associated Followers have been placed in the box, the membrane can easily be spread over the follower, leaving the peripheral edges of the membrane can be placed airtight on the top of the box. Now vacuum can be created in the box below the membrane, whereby the membrane, as a result of the atmospheric pressure on its upper side, is pressed tightly against the follower and so the intended pressing effect is achieved.

The invention is now with reference to the drawing in which a non-limiting embodiment of the device according to the invention is reproduced, explained.

Fig. 2 is a front view of the device and

Membrane.

The device according to the invention consists of one on the top open rectangular box 1 with a bottom 2 inclined towards the center and upstanding longitudinal and transverse walls 3 and 4, respectively. In the middle, that is at the lowest point of the floor, an opening 5 is provided, which connects the box with a whey collecting container 6 arranged below it, which container is provided with a drain tap 7 is.

The box can be placed on a frame 8 with legs 9 and swivel wheels 10 rest for easy shifting.

As Fig. 3 shows schematically, the contacting cheese molds 11 arranged according to straight longitudinal and transverse rows in the box. Also, the top surface is a follower 12 shown in FIG. 3 visible.

Distributed at regular intervals over the upper circumference of the box, are known clamp fasteners 13 with actuating levers 14 arranged, which fasteners on transverse flanges 15 of the upright Walls 3 »4 rest. These closures are intended to form a frame

16 by means of sealing members 17, 18, of which the member I7 is elastic is to press against the flanges. Before the frame is arranged, the flexible membrane 19 is as taut as possible on the sealing members

17 placed, whereupon the frame is arranged and clamped. Through this what is achieved is that the membrane seals the upper side airtight and rests on the upper surfaces of the followers 12.

Via a connection piece 20 (see FIG. 1), by means of a line (not shown) connected to this, after a vacuum pump (not shown), vacuum is generated in the box, namely in the spaces between the coffee molds under the membrane. The membrane is now given the shape shown in FIG. Everything there has to

As a result, atmospheric pressure is exerted on the outside of the followers and the curd is pressed into the cheese molds will. Of course, the drain cock 7 should be hermetically sealed while the vacuum is being generated.

The whey that flows over the edge of the cheese molds when pressed through the inclined box floor into the collecting container 6.

To ensure correct stretching of the membrane, this is with a thickened edge 21 is provided.

It is also possible to frame the frame with one of the long or short sides to articulate the box and to arrange the clamps only on the other upstanding walls.

Other, purely structural changes are possible without leaving the The scope of the invention will occur.
