Problems solved by technology

For liquid foods comprising solids and optionally of low viscosity, such as fruit juices with fibres, pulp, fruit pieces, sacks or the like or milk products with additives, this mechanical stress can be at the throttle point ( damage rate) damages more solid components in relatively narrow gaps and thus sustains damage to the quality of the food being processed
Another disadvantage is that solids are deposited in the narrow throttle gap and from time to time strengthen the predetermined throttling effect so that the predetermined pressure difference cannot be maintained with sufficient uniformity during decompression
Decompression only through at least one throttling gap can also lead to undesired heating or cavitation, which is detrimental to both the food and the control valve

Embodiment Construction

[0021] The device V is used, for example, in filling technology for fruit juice or milk products or the like. The device V is especially suitable for liquid foods comprising solids such as fibres, pulp, pieces of fruit, pieces of fruit and the like, but can also be used for making beer (for example for wort) or for filling yoghurt with additives. during installation.

[0022] The device V has a heat exchanger W defining, for example, a preheating section 1 , in a predetermined product flow from the storage 15 through the supply section 2 , for example by means of an electric feed pump 3 at a predetermined feed pressure P1 , which will contain solids The liquid food P of T is conveyed through the preheating section 1, and the liquid food P is heat-treated such as pasteurization or the like. The supply pump 3 is connected to the electric motor 4 . An electric motor 4 can be included in the charge pump 3 and is connected in an embodiment to a frequency converter 5 , which recei...

Abstract

In a device for treating a liquid foodstuff product containing a solid with a heat exchanger charged with the foodstuff product under pressure and / or a degasser, which is charged with a reduced pressure, followed or preceded by a pressure reduction device, the pressure reduction device has at least one brake pump through which the foodstuff product flows. In a method the pressure with which the foodstuff product is conveyed through the brake pump is reduced by a rotary movement of the brake pump.

Description

technical field [0001] The invention relates to a device for processing liquid food and a method for processing liquid food. Wherein said liquid food contains solids, said device has a heat exchanger and / or degasser for said food, and a decompression device is provided before or after said heat exchanger and / or degasser. Background technique [0002] In the filling technology of liquid food products such as fruit juices, milk products or the like, devices are used, for example for pasteursing and / or degassing, in which the food product is degassed under pressure Passed through a heat exchanger and then optionally fed to a degasser (eg, vacuum vessel). In terms of high productivity and efficient heat exchange and precisely controllable product flow, the food product is conveyed through the heat exchanger under relatively high pressure. This high pressure has to be eliminated or at least significantly reduced in further processing steps downstream of the heat exchanger, espe...
