I had pre-processed it so that it would work. Also, if fresh grass for livestock is not available, use Chigusa. It is also known to use However, if these plants are dried in the air or in a drying factory, If this happens, most of the proteins in the plant will be destroyed and the liquid in the plant will be lost. become. In addition, in known drying factories, some combustion residue adheres to the dried raw materials. quality may be compromised. Furthermore, oil is used as heat energy in the drying factory. This causes high costs. Therefore, plants with low plant fiber content Drying treatment becomes virtually impossible.

Therefore, the object of the present invention is to use relatively low energy consumption and to use hydrocarbons such as oil. Processes various plant materials into desired products without using natural thermal energy. Our goal is to provide a method that allows for the production of valuable materials such as tan and yak material. We aim to create products with minimal loss of quality that can be used as food for humans and animals. The purpose is to provide.

According to the present invention, these objectives are achieved by mechanically treating the plant material to separate it into a liquid phase and a solid phase. Then, the protein-containing solid phase is made into a dry product, while the protein-containing liquid phase is agglomerated. This is achieved by separating this agglomerate from the residual liquid and then drying it. Ru.

The apparatus for carrying out the above method of the present invention includes a mechanism for pulverizing the raw material and a mechanism for pulverizing the pulverized material.

The supply roller 12 feeds the raw material onto a conveyor belt 15, and then a rotary crushing mechanism 16. supplied to This crushing mechanism 16 is a double disk IJ.

- It consists of an extruder, by which the raw material is divided into pieces and squeezed out, i.e. it becomes a solution. and some of that diesel is removed.

A roller squeezer or gies press is provided downstream of the crushing mechanism 16, The raw material is separated into a liquid phase and a solid phase. That is, the press 17 has a rotating roller 18. , the raw material fed into the filter means is forced out by rollers. At the same time, the solid phase It is sent to a drying and blocking mechanism 20 by a pipe 19. This mechanism 20 is , - an extruder is provided. Here, the proper fraction is dried and pressure-molded into pellets. will be made into a cut. This hardened product is the final product, and after that, especially It does not require any processing. The pellets are simply cooled on the conveyor belt 21. and then stored, packaged, or transported.

The liquid phase obtained by the horizontally arranged roller press 17 is collected in a container 22, The substance in the liquid is conveyed via line 23 into a flocculating device 24 and the substance in the liquid is collected by a flocculating medium 25. is agglomerated. This flocculation medium is, for example, heat, natural or artificial fermentation agents. This stiffness Concentrator 24 can be operated continuously or in batch mode.

This flocculated liquid is sent to a roller press 27 via a line 26, where it is flocculated. fraction is separated from the residual liquid. This press 27 has the same configuration as the press 17. It can also be arranged horizontally.

The agglomerated matter is sent via line 28 to a drying and blocking mechanism 29, where it is dried. The pellets are then pressure-molded into pellets, and then cooled on a conveyor belt 3o. , sent to the next processing mechanism. This drying and blocking mechanism 29 is the same as the previous drying and blocking mechanism 29. It may be similar to the converting mechanism 20.

The residual liquid obtained in the roller press 27 is collected in a container 31 and sent via line 32. and is discharged. FIG. 2 shows a container 33 for containing residual liquid gold.

This residual liquid can also be used as feed for certain fish.
