Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of turning, in particular to an automatic turning system. BACKGROUND

[0002] In the brewing process, after the distiller's grains are steamed, the distiller's grains need to be added with koji in the spreading process to facilitate the subsequent fermentation of the distiller's grains in the cellar. The koji is made by a koji making machine, and the koji block made by the koji making machine needs to be fermented in a koji room. The existing post-koji-making process (i.e. the subsequent process after the koji block comes out of the koji making machine) is very backward in automation, and the relevant operations are mainly performed in an artificial manner: the koji block is manually taken to the corresponding shelf, and after the koji block is fermented for a certain period of time, the koji block is manually turned over. Because the temperature of the upper layer and the lower layer in the koji room is inconsistent, in addition, the moisture of the upper part and the lower part of the koji block is inconsistent due to the influence of gravity, in order to avoid the moisture of the koji block from being lost too quickly and to ensure the uniformity of the temperature of the koji block, the koji needs to be turned over every certain period of time, and the traditional turning over is also performed in an artificial manner, i.e. the koji block is turned over by 180°. It can be seen that the traditional manual labor is intensive and the work efficiency is low; in addition, the temperature in the koji room is as high as 50℃ and the humidity is as high as 95%, the working environment is very poor, and it is difficult to recruit workers.
