TH44151C3 - Methods and machines for pressing expanded water-retained products such as foodstuff powders or feed pellets. - Google Patents

Abstract

DC60 (04/10/55) In the press of feed pellets and related consumer products, Products that have been The compression was expanded as a result of the boiling of its water-based contamination. After the product has been subjected to high compression pressure and corresponding high temperature, it is discharged into the atmosphere through the compression pipe. The expansion is what is the direct aim of But it is desirable to be able to control it. It was difficult by modulating the conventional process parameters for this invention, it was discovered that the expansion which took place could be controlled. This can be done in a very stable manner, that is, by pressing into a closed chamber where the pressure exceeds a few bar. Has been made in relation to atmospheric pressure. And can be controlled Press products It can be continuously drained from this hole. Alternatively, the product can be ventilated in portions with overpressure, causing the momentary steam generation in the compression product to be mitigated and the product is time to stabilize before it is emptied. In the press of animal feed pellets and related consumer products, the subsequent generation of water vapor has little effect on the structure of the product. Products that have been The compression was enlarged as a result of the month of its aqueous content. After the product has been subjected to high compression pressure and corresponding high temperature, it is discharged into the atmosphere through the compression pipe. The expansion is what is the direct aim of But it is desirable to be able to control it. It was difficult by modulating the conventional process parameters for this invention, it was discovered that the expansion which took place could be controlled. This can be done in a very stable manner, that is, by pressing into a closed chamber where the pressure exceeds a few bar. Has been made in relation to atmospheric pressure. And can be controlled Press products It can be continuously drained from this hole. Alternatively, the product can be ventilated in stages, the overpressure causes the momentary steam generation in the compression product to be mitigated, and the product is time to stabilize before it is emptied. This causes the subsequent generation of water vapor to little effect on the structure of the product.

Claims (9)

Disclaimers (all) that will not appear on the advertisement page: 1.Compression machinery Especially for the production of products which expanded by Heating of the process is related by internal boiling of water by releasing the pressure after The route of the product is passed through the compressed mouth (10), that is, food or animal feed. That machine It consists of a pipe mouth unit (8) and a route (2,6) for pressing out the product material through the pipe mouth (10), characterized by that on the outlet side of the pipe mouth unit (8), the pressure chamber (16) that is connected. To receive The product is temporarily placed directly from the mouth unit (8). Such pressure chambers (16) will be connected to the Pressure regulating path (28,31) for maintaining the desired adjustable pressure in the pressure chamber (16). 2. Methods consistent with claim 1, where the pressure Too much in the pressure chamber is mainly regulated by a regulated outlet of the steam that Caused by compressed products 2. Method consistent with claim 1, where the compression Has been acting continuously And the product has been drained Out at that moment by using the pouring arrangement Or, optionally, the compression was performed intermittently and the product was Receive a series of discharges from the said pressure chamber. 4.Compression machinery Especially for the product Which expands by heat Of the processes involved The internal boiling of the water by releasing the pressure after passing through the product in the compression tube mouth. Such as foodstuffs or animal feed by the said machine consisting of units Pak Tho and the means for Extraction of product materials through the mouth of the pipe. With unique characteristics which On the vent side Of the Pak Tho unit There is a pressure chamber for the The product is temporarily suspended from the mouthpiece unit. The aforementioned pressure chamber is connected to the pressure regulator. For the treatment of excessive pressure which is Desired and can be adjusted in this box. 5. Machine that complies with claim 4, with the characteristics of which the component control device With regulated release valve For modulating the pressure build-up which has already been achieved by releasing steam from the compressed product. 6. Machine that complies with claim 5, with the characteristics of which the pressure regulator Also contains a control valve Pressure for feeding compressed air to the pressure chamber. 7. Machine corresponding to claim No. 4, with the characteristics of which the pressure regulator Has been arranged to maintain 1/2 - 6 bar overpressure in the pressure chamber 8. Machine corresponding to claim 4, with the characteristics in which the pressure chamber is Set for action Continuously It is provided with a vent design for the continuous discharge of the compressed product. 9. A machine corresponding to claim 4, with the characteristics in which the pressure chamber is It is intended for intermittent operation, that is, for the discharge of the accumulated bulk of the pressed product, respectively, by simple exposure to the atmosphere. 0. Unit for assembly in a unique compression machine, it consists of The channel for installation is provided. Tightly attached to the outlet end of the pipe fitting in the machine formation corresponding to Clause 4, the aforementioned port contains an ejection valve for steam and a path for discharging the product from it.
