Description

Technical Field

[0001] This utility model relates to the field of brewing technology, and in particular to a molding device for yeast blocks. Background Technology

[0002] Brewing is a traditional Chinese craft with a long history. In particular, the process of brewing baijiu (Chinese white liquor) involves washing, crushing, distilling, adding yeast, and fermenting basic agricultural crops such as rice, sorghum, and wheat to produce mellow and fragrant baijiu.

[0003] In the production of yeast starter, loose yeast needs to be compressed into blocks for convenient transportation and storage. However, existing yeast block forming processes have two main problems: First, they rely on manual operation, where material is manually filled into molds and manually extruded. This method is not only slow, but also produces yeast blocks that are not dense enough and are prone to crumbling. Second, simple forming devices are used for extrusion molding, but it is difficult to precisely control the weight of yeast added each time, resulting in inconsistent sizes of the formed yeast blocks.

[0004] In view of the above-mentioned related technologies, the inventors believe that there is a need to provide a molding device for yeast blocks. Utility Model Content

[0006] By adopting the above technical solution, the loose yeast is first fed into the feeding hopper. Then, two spiral conveyor rollers rotate in opposite directions to transport the loose yeast from the feeding hopper to the forming mold. Subsequently, the cutting component installed inside the machine housing and located at the exit end of the forming mold can cut the formed yeast into yeast blocks of the required length. Finally, the powder brushing mechanism can brush the surface of the cut yeast blocks with powder, which can effectively solve the problems of slow forming speed and small size in the existing process.

The rotary drive 23 uses a common small motor. The two spiral conveying rollers 22 rotate relative to each other, which can convey the yeast material in the feeding bin 21 towards the forming mold 24. Through the rotation and extrusion of the spiral conveying rollers 22, the yeast material can be initially compacted, preparing for subsequent forming.

[0037] Reference Figure 3 and Figure 4The molding die 24 is equipped with a molding mounting sleeve 241 for installation onto the outlet end of the feed hopper 21. The inner wall of the molding mounting sleeve 241 is provided with an internal thread 2411, and the outlet end of the feed hopper 21 is provided with an external thread 211 that mates with the internal thread 2411. Through the threaded connection, the molding die 24 can be easily installed and disassembled, facilitating the replacement of molds of different shapes and sizes to produce yeast blocks of different specifications. The molding mounting sleeve 241 is provided with a locking protrusion 2412 for pressing the molding die 24. The locking protrusion 2412 ensures a tight connection between the molding die 24 and the feed hopper 21, preventing leakage of yeast materials.

The housing 1 is provided with a mounting bracket 11 for installing the bacterial powder box 31. The mounting bracket 11 has an oblong hole 111. The bacterial powder box 31 has a mounting through hole 312 corresponding to the oblong hole 111. The mounting bracket 11 is provided with a bolt pair 112 for fixing the bacterial powder box 31 at the oblong hole 111. Through the design of the oblong hole 111, the installation position of the bacterial powder box 31 can be adjusted to a certain extent to ensure that the position of the bacterial powder outlet 311 and the conveyor seat 12 is relatively accurate. In this embodiment, the bolt pair 112 consists of a bolt and a nut that mates with it.

[0041] Reference Figure 5 The housing 1 is inclined below the yeast powder outlet 311 and a conveyor seat 12 is provided. The outlet end of the conveyor seat 12 extends to the outside of the housing 1. The inclination angle of the conveyor seat 12 can ensure that the yeast blocks slide down by their own gravity, and at the same time, it can receive the yeast powder falling from the yeast powder outlet 311 during the slide, realizing a free-fall rolling powder brushing operation.

The horizontal side door 15 and the top cover 16 are connected to the housing 1 by hinges or latches, which can be easily opened and closed, facilitating the maintenance and repair of the internal powder brushing mechanism 3 and molding die 24.

[0043] Reference Figure 7 The storage box 4 is located at the discharge port of the conveyor seat 12 and has an open top. Inside the storage box 4 is a storage core 41 for storing materials. The top of the storage core 41 has an outwardly extending placement protrusion 411, and the bottom of the storage core 41 has several discharge holes 412 for the outflow of yeast powder. A storage gap 42 is formed between the bottom of the storage box 4 and the bottom of the storage core 41. By setting an open-top storage box 4 at the discharge port of the conveyor seat 12 and installing a storage core 41 with placement protrusions 411 inside the storage box 4, the cut and powdered yeast blocks can be stored. The discharge holes 412 at the bottom of the storage core 41 and the storage gap 42 between the bottom of the storage box 4 and the bottom of the storage core 41 allow the yeast powder carried by the yeast blocks to flow smoothly to the bottom of the storage box 4. The outflowing yeast powder can also be recycled. In addition, to facilitate the operation of operators to pick up or transport the cut and powdered yeast blocks, a pick-up handle 4111 is provided on the placement protrusion 411.

First, the loose yeast is fed into the feeding hopper 21. Then, two spiral conveying rollers 22 rotate relative to each other to convey the loose yeast in the feeding hopper 21 to the forming mold 24. The forming mold 24 can compress the yeast into the required shape. Then, the forming yeast is cut into yeast blocks of the required length by the cutting component 25. Through the powder brushing mechanism 3 and the conveying seat 12, the yeast can be freely rolled and powdered on the conveying seat 12 under the action of gravity. Finally, the yeast blocks fall into the storage core 41 under the action of gravity, and the excess yeast powder enters the storage gap 42 through the discharge hole 412.
