Description

Buckling die assembly, buckling die kneading assembly, buckling machine and buckling method

Technical Field

The invention relates to the technical field of wine making, in particular to a koji-pressing die assembly, a koji-pressing die kneading assembly, a koji-pressing machine and a koji-pressing method.

Background

In the process of making the white spirit, the yeast material is required to be pressed into yeast blocks. The quality and style of the liquor are greatly influenced by the making process of the yeast blocks and the quality of the yeast blocks, and particularly the famous high-quality liquor has higher requirements on the making of the yeast blocks. In order to improve the pressing efficiency and the pressing quality of the koji blocks, various automatic koji pressing devices are designed. In order to improve the pressing efficiency and automation, a bending press is designed, for example, a bending press for continuous stamping and forming disclosed in prior art CN101857828B, which includes a frame, a chain box transmission device fixed on the frame for transmitting a chain box for forming a bending block, a bending material conveying device for conveying bending materials into the chain box, and a pressure assembly for pressing and forming the bending materials in the chain box. When a koji block is manufactured, a koji material is conveyed into a chain box through a koji material conveying device, the chain box moves the chain box carrying the koji material to the lower part of a pressure assembly under the action of a chain box transmission device, and then the pressure assembly is started to enable a pressing die of the pressure assembly to move downwards and press and form the koji material in the chain box; and then the pressing die of the pressure assembly is withdrawn from the chain box, the chain box is moved to an unloading station under the action of a chain box transmission device, and the pressed and formed bent blocks in the chain box are unloaded through an unloading device.

Although the existing koji pressing machine can greatly improve the working efficiency and reduce the labor cost, the pressure assembly is a straight-up and straight-down single action device, so that the full paste lifting effect which is the same as that of manual koji pressing cannot be obtained. And during the yeast pressing, the yeast blocks are required to be in a tortoise back shape, the appearance of the yeast blocks is tight, and the middle of the yeast blocks is loose, so that a certain amount of air can enter the yeast blocks, and the growth and the propagation of aerobic microorganisms can be met. The density of the mechanical koji making is hard to be consistent with the density of the internal distribution of the koji blocks when the mechanical koji making is performed with manual koji treading, so that the internal part of the mechanically koji making is too tight or too loose, and the fermentation of the koji blocks is not facilitated. Therefore, in order to ensure the high quality of the koji making, the distillery still keeps the koji making mode of manually treading the koji. Aiming at the above, in order to ensure the koji making efficiency and improve the quality of koji blocks, the structure of a koji pressing die in a koji pressing assembly needs to be changed so as to simulate manual koji treading during koji pressing, thereby obtaining high-quality koji blocks, improving the koji making efficiency and reducing the labor cost.
