Technical Field
[0001] This utility model relates to the field of fermented bean curd processing technology, and in particular to a fermentation device for the production of fermented bean curd. Background Technology
[0002] Fermented bean curd, also known as tofu curd, is a fermented soy product. It is a popular and enduring delicacy due to its delicious taste and high nutritional value. Fermented bean curd is generally believed to lower cholesterol. The unsaturated fatty acids in it can help eliminate excess cholesterol from the body, thus reducing cholesterol levels. Furthermore, it is rich in plant protein. During fermentation, the protein breaks down into various amino acids and produces yeast and other substances that aid digestion. Because fermented bean curd is believed to stimulate appetite and promote digestion, it is suitable for people with poor appetite. The fermentation process involves using fermentation equipment to ferment the fermented bean curd starter.
[0003] CN219409711U discloses a prefabricated fermentation device for fermented bean curd, including a fermentation box. The fermentation box has an internal assembly structure, including side plates fixed to both sides of the fermentation box. Each side plate has a pre-reserved groove. The fermentation box contains a fermentation sieve, with a surrounding plate fixed to the top edge of the sieve. A sealing ring is fixed to the edge of one end of a door panel, and a magnetic strip is fixed inside the sealing ring. This device allows for the assembly of the fermentation sieve. When removing material, pulling the handle pulls the fermentation sieve out of the pre-reserved groove, facilitating material removal. Fermented bean curd requires stratified cultivation of mycelium during the early fermentation stage, but the fermentation sieve structure in this device is relatively simple, lacking a cover structure at the top, making it impossible to inoculate the fermented bean curd by turning it over, thus affecting fermentation efficiency. Therefore, a fermentation device for fermented bean curd production is needed. Utility Model Content

[0026] Please see Figure 1-5 This utility model provides a technical solution: a fermentation device for fermented bean curd production, comprising a fermentation box 1 and a fermentation sieve installation structure. The fermentation sieve installation structure includes a first fermentation sieve A11, a second fermentation sieve B12, a slide rail 13, a first placement frame A15, a second placement frame B16, an insertion rod 17, and an insertion hole 18. Multiple first fermentation sieves A11 are equidistantly slidably connected inside the fermentation box 1. The number of second fermentation sieves B12 is the same as that of the first fermentation sieves A11, and they are equidistantly slidably connected inside the fermentation box 1. The first fermentation sieves A11 and the second fermentation sieves B12 are perfectly shaped. All are identical. There are multiple slide rails 13, all of which are fixedly connected to the two sides of the surface of the corresponding first fermentation screen A11 and the second fermentation screen B12. The number of first placement frames A15 is the same as that of the first fermentation screen A11, and all of them are fixedly connected to the top of the corresponding first fermentation screen A11. The number of second placement frames B16 is the same as that of the second fermentation screen B12, and all of them are fixedly connected to the bottom of the corresponding second fermentation screen B12. There are multiple insertion rods 17, all of which are fixedly connected to the bottom of the second placement frame B16. The number of insertion holes 18 is the same as that of the insertion rods 17, and all of them are opened on the top of the first placement frame A15. The insertion rods 17 and insertion holes 18 are engaged.
[0027] Furthermore, the surfaces of the first fermentation sieve A11 and the second fermentation sieve B12 are each provided with multiple sieve holes 14 for ventilation. The surfaces of the first placement frame A15 and the second placement frame B16 are each provided with placement slots 19 for holding fermented bean curd. The inner wall of the fermented bean curd fermentation box 1 is provided with multiple sliding grooves 20 that are adapted to the sliding rail 13. A heating plate 10 is fixedly connected inside the fermented bean curd fermentation box 1. A temperature controller 2 is fixedly connected to the surface of the fermented bean curd fermentation box 1. A protective top cover 7 is fixedly connected to the top of the fermented bean curd fermentation box 1. A humidifier 8 is fixedly connected to the top of the fermented bean curd fermentation box 1. Multiple output pipes 9 are fixedly connected to the output end of the humidifier 8. Each output pipe 9 extends into the interior of the fermented bean curd fermentation box 1. A humidity controller 3 is fixedly connected to the surface of the fermented bean curd fermentation box 1. The humidity controller 3 is electrically connected to the humidifier 8. A fermentation box door 5 is rotatably connected to the surface of the fermented bean curd fermentation box 1. A door handle 6 is fixedly connected to the surface of the fermentation box door 5. Multiple device bases 4 are fixedly connected to the bottom of the fermented bean curd fermentation box 1.
[0028] Further, the fermented bean curd is placed on the placement slot 19 of the first placement frame A15. Then, the second fermentation sieve B12 and the second placement frame B16 are brought close to the first placement frame A15. The insertion rod 17 on the second placement frame B16 is inserted into the insertion hole 18, achieving initial fixation between the first placement frame A15 and the second placement frame B16. Then, the slide rail 13 is aligned with the slide groove 20 on the inner wall of the fermented bean curd fermentation box 1, so that the first fermentation sieve A11 and the second fermentation sieve B12 are slidably installed inside the fermented bean curd fermentation box 1. Due to the restriction of the slide groove 20, the first fermentation sieve A11 and the second fermentation sieve B12 can fit tightly together. Then, the fermentation of fermented bean curd is carried out. When turning the fermentation screen, the first fermentation screen A11 and the second fermentation screen B12 are installed in opposite directions inside the fermentation box 1. The humidifier 8 installed on the fermentation box 1 can humidify the inside of the fermentation box 1, thereby regulating the humidity inside the fermentation box 1. The heating plate 10 can heat the inside of the fermentation box 1, thereby regulating the temperature inside the fermentation box 1. The temperature controller 2 and the humidity controller 3 can control the start and stop of the heating plate 10 and the humidifier 8. The temperature controller can be referred to in the announcement number CN215250758U.
[0029] Furthermore, the fixed connection between the first fermentation screen A11 and the second fermentation screen B12 enables the storage and fermentation of fermented bean curd, and allows for inversion, which facilitates inoculation of fermented bean curd and makes the device more flexible. This solves the problem that the fermentation screen in the device has a relatively simple structure and lacks a cover structure on the upper part, which makes it impossible to inoculate fermented bean curd by inversion and affects fermentation efficiency.
