Abstract
Description
Technical Field
[0001] This application relates to the field of constant temperature stirring technology for beer, specifically a constant temperature stirring device for whey beer production. Background Technology
[0002] The origin of beer is closely related to the origin of grains. Humans have been using grains to make alcoholic beverages for many years. Beer is an alcoholic beverage made from wheat malt and barley malt as the main raw materials, with the addition of hops, through liquid gelatinization and saccharification, and then through liquid fermentation.
[0003] Currently, beer thermostatic stirring devices typically have heating and cooling mechanisms installed on the outside of the stirring drum to maintain a constant beer temperature. However, the stirring drum has a certain internal space, and temperature transfer often occurs from the outside to the inside, making temperature control relatively difficult and thus affecting the quality of beer production. Utility Model Content
[0004] The purpose of this application is to provide a constant temperature stirring device for whey beer production, which solves the problem that the constant temperature stirring devices for beer mentioned in the background art generally set heating and cooling mechanisms on the outside of the stirring drum to keep the beer at a constant temperature. However, the stirring drum has a certain internal space, and the temperature transfer is often from the outside to the inside, making it difficult to control the temperature and thus affecting the quality of beer production.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This application provides a constant temperature stirring device for whey beer production, including a stirring drum. A stirring rod is rotatably mounted on the inner top wall of the stirring drum. Multiple sets of stirring blades are welded to the outer walls of both sides of the stirring rod inside the stirring drum. Two sets of air chambers are respectively opened in the inner walls of the stirring rod and the stirring blades. A set of through holes is respectively opened on the outer wall of the stirring blades on one side of the two sets of air chambers. A double-channel rotary joint is installed at the upper end of the stirring rod. Two sets of air injection pipes are installed at the upper end of the double-channel rotary joint.

In turn, the first bevel gear can drive the stirring rod to rotate, and the stepper motor is fixedly installed with the first bevel gear through a coupling.

[0017] By adopting the above technical solution, the cleaning pipe can be connected to the water injection pipe of the external equipment, and the second valve can close and open the cleaning pipe. When the first valve is closed, the second valve is open, and the two are in an open and closed state. Then the water inside the cleaning pipe can be discharged from the air chamber, thereby cleaning the stirring rod and the inner wall of the stirring blade.
[0018] Optionally, a fixing ring is fixedly installed on the outer wall below the stirring cylinder, and multiple sets of support legs are fixedly installed at the lower end of the fixing ring.

When the first valve 7 is closed, the second valve 9 is open. The two are in an open and closed state, and the water inside the cleaning pipes 8 can be discharged from the air chamber 4, thereby cleaning the inner walls of the stirring rod 2 and the stirring blade 3.
[0034] In the technical solution of this application, such as Figure 1 As shown, the driving mechanism includes a stepper motor 12 mounted on the upper end of the stirring drum 1. A second bevel gear 11 is fixedly mounted on the output shaft of the stepper motor 12.
