Square filtering tank for beer saccharification filtering system

Abstract

The invention discloses a square filtering tank for a beer saccharification filtering system, and relates to a filtering system special for beer saccharification. The square filtering tank comprises a filtering plate, an exhaust barrel, a vinasse discharging lifting device, a vinasse raking reciprocating device, a tank washing water inlet, a washing water inlet, supporting legs, a mash inlet, a backwashing water inlet and a wheat juice outlet, wherein the exhaust barrel is fixed at the top of a tank body; the vinasse discharging lifting device and the vinasse raking reciprocating device are arranged on the tank body in a sliding manner and are both connected with a large vinasse raking arm in the tank body; the tank washing water inlet is also formed in the tank body; the washing water inlet is formed in the side surface of the tank body; the mash inlet is formed below the washing water inlet; the filtering plate is arranged in the tank body; a vinasse discharging door is arranged on the filtering plate; the backwashing water inlet and the wheat juice outlet are formed in the lower end of the tank body. According to the square filtering tank for the beer saccharification filtering system, the linear speeds of raking cutters in the tank during vinasse raking are consistent, so that the original concentration of the collected wheat juice at different positions after mash is filtered is the same, and the pure flavor of wheat juice is guaranteed.

Description

technical field [0001] The invention relates to a special filter system for beer saccharification, in particular to a square filter tank for the beer saccharification filter system. Background technique [0002] The quality of wort filtration in the beer brewing process directly affects the composition of wort and whether the fermentation and filtration can proceed smoothly. Therefore, wort filtration plays a vital role in the beer brewing process. The traditional cylindrical filter tank The structure is shown in Figure 1. After the saccharification mash enters the filter tank, the mash is plowed through the device 1 to obtain the soluble extract in the saccharification mash. After adding the washing water, the saccharification The residual soluble extract in the mash passes through the filter plate 2 and the wort collection ring pipe 3, filters and collects the wort to the wort temporary storage tank or directly pumps it to the boiling pot, and then passes through the plowi...

Problems solved by technology

[0003] It can be seen from the structural diagram of the plowing and arranging device 1 that different forms of plowing knives are hung on the big arm of the plowing dregs from the inside to the outside. The four to six tillage arms fixed on the main shaft in the groove drive the cultivator to make a circular motion around the main shaft for tillage. However, the linear speed of the inner and outer rings of the tiller suspended on the tiller arm is different. The speed ratio relationship between the two is D (inner): D (outer). Take the traditional 65M3 saccharification as an example: the diameter of the inner ring of the filter tank is 2300 mm, and the diameter of the outer ring is 8250 mm. The ratio is 2300:8250, about 1:3.6. The difference in linear velocity causes the friction force between the plow blade and the material in the bad layer to be different during plowing, and the original concentration of wort in different positions is different, which in turn affects the quality of wort filtration.
