Beer saccharification filter device using coil pipe for heating

Abstract

The invention discloses a device for saccharifying and filtering beer which is heated by a coil. The device comprises a saccharification filter tank and a hot water tank, wherein, a sieve plate for filtering is arranged above the tank bottom of the saccharification filter tank. The device is characterized in that a mash outlet is arranged at the tank bottom of the saccharification filter tank, a mash refluxing port is arranged on the saccharification filter tank above the sieve plate; the coil is arranged inside the hot water tank, a mash outlet of the coil is connected with the mash refluxing port on the filter tank by a pipeline, a mash inlet of the coil is connected with the mash outlet on the saccharification filter tank by a pipeline, and a centrifugal pump is arranged on the pipeline between the mash inlet of the coil and the mash outlet on the saccharification filter tank. The device has the advantages of keeping constant temperature in the course of the saccharification and being capable of carrying out multi-temperature saccharification, and is particularly applicable to beerhouses at places such as guesthouses, hotels, etc.

Description

technical field [0001] The invention relates to the field of beer brewing, in particular to beer saccharification and filtering equipment for a beer house. Background technique [0002] Existing beer house wort preparation system is mainly based on two devices and three devices, and generally all includes saccharification filter tank and hot water tank. See "a combined beer wort preparation device" disclosed in the applicant's Chinese invention patent application ZL200810059200.9. [0003] Malt is saccharified in the saccharification lauter tank with hot water in the hot water tank, and there is no heating device in the saccharification lauter tun, which is still a relatively traditional and popular form of mashing equipment in beer houses. [0004] The advantage of this form is that the saccharification lauter tank does not require a heating jacket, does not require mechanical stirring, and does not cause coking. But there are also the following problems: [0005] During...

AI Technical Summary

Problems solved by technology

[0005] During the saccharification process, due to heat conduction and radiation heat transfer between the material in the tank and the external environment, the temperature of the material in the tank is constantly decreasing, and it is difficult to keep it constant.

This has brought about many problems: firstly, due to the drop in temperature, the malt cannot be kept at the temperature section with the highest enzyme activity for a long enough time, resulting in a decrease in saccharification yield; secondly, due to the drop in temperature, the bad layer will shrink, making filtration difficult ; Third, only single-temperature saccharification can be carried out, and the diversity of brewing processes in beer houses cannot be realized; Fourth, saccharification first and then filtration takes up a long time in the pot
