SU100414A1 - The method of progressive pre-defecation diffusion juice - Google Patents

Description

The method of progressive pre-defecation of diffusion juice by adding to it unfiltered juice of the first saturation is known. The disadvantage of this method is a certain complexity of the process, due to the fact that in the pre-adefekator the unfiltered juice of the nerve saturation is mixed with the diffusion juice, and then progressive lime limiting is performed.

The proposed method is free from this drawback, since the pre-defecation partially overlaps with the main one. This is achieved by adding to the diffusion juice the otgazovanny juice of the first saturation with lime milk.

According to the proposed method, the pre-defecation is performed as follows.

Normally otgazovanny unfiltered juice of the first saturation is returned to the device. On the way to the pre-blender, this juice is alkalized with lime milk to an alkalinity of 0.25%. The alkalinity of the pre-defecation is adjusted to 0.10% CaO.

The drawing shows the setup scheme for the implementation of the proposed method.

The raw juice from the measuring device / pump 2 is supplied to the resofers 3. The beetroot juice heated in the latter passes through the float skimmer to the pre-blender 4, and the last 13 to the defecators 5 of the main defecation. The milk of lime into the defecators 5 comes from the measuring device 6. From the defecators the diffusion juice is sent to the saturators 7 of the first saturation.

The pre-defector is made in the form of a vertical cylindrical boiler with an internal heating pipe running from bottom to top with a pipe provided with a longitudinal slot in the wall. The lower end of the pipe is plugged. The heated diffusion juice from the reshofers is introduced into the lower part of this pipe.,

In the same pipe, pump 8 is supplied with otgazovanny juice of the first saturation, along with lime milk, which is introduced into the suction line 9 of the pump 8. From the saturators 7, unfiltered juice of the first saturation is fed by pump 10 through rester 11 to the filter press 12; Further

The juice purification process is carried out in the usual manner.

The amount of juice of the first saturation returned to the predefinition is 75-80%.

The consumption of milk of lime for the purification of juice during the defecation of diffusion juice but the proposed method is lower than with previously known methods, and the quality of cleaning is higher.

Subject invention

The method of progressive precursor defecation of the diffusion juice with the juice of the first carbonation, oh and h and y with the fact that, in order to simplify the process, at the preliminary defecation, the carbonated juice of the first carbonation with lime milk is added to the diffusion juice.
