Description

Technical Field

[0001] This utility model relates to the field of solid-state fermentation equipment for Monascus purpureus, and in particular to a turning device for solid-state fermentation of Monascus purpureus. Background Technology

[0002] Red yeast rice, a traditional Chinese medicine, is artificially cultivated by inoculating rice (withered kernels) with the fungus *Monascus purpureus*. It is used for symptoms such as abdominal distension, poor appetite, shortness of breath, fatigue, dizziness, and headache caused by spleen deficiency and food stagnation. It can also be used as an adjunct treatment for hyperlipidemia and atherosclerosis. Clinical human trials, patient follow-up observations, and animal experiments have shown that red yeast rice has a comprehensive lipid-regulating effect, effectively controls the disease, reduces mortality, and has high safety with few toxic side effects. It can be taken long-term and is a commonly used and effective medicine for the clinical treatment of hyperlipidemia and related diseases caused by hyperlipidemia and atherosclerosis.

[0003] However, red yeast rice is fermented in a bottle in solid state. Carbon source, nitrogen source, inorganic salt and water are added to the rice. After high-temperature cooking and sterilization, the rice becomes sticky. In the early stage of fermentation, the red yeast fungus grows rapidly, multiplying in number. The mycelium is dense, fluffy, and well-branched, wrapping around the rice. The fermentation substrate is very prone to clumping.

[0004] Currently, in the red yeast rice industry, manual knocking and turning of the fermentation bottle are commonly used to break up clumps during fermentation. However, manual turning is time-consuming and labor-intensive, and it is difficult to effectively and evenly break up the clumps. Furthermore, the internal temperature of the clumps rises, aeration is insufficient, and fermentation is incomplete, which is detrimental to the synthesis of lovastatin, a key component of red yeast rice, resulting in low lovastatin content. Clumping also easily leads to uneven color and poor appearance of the fermented product. It also causes uneven moisture distribution during fermentation, with more moisture at the bottom of the bottle and less at the top, resulting in inconsistent color and poor appearance of the fermented red yeast rice product. This makes it unsuitable for sale as normal red yeast rice medicinal slices, leading to waste of production materials and increased production costs. Therefore, manual knocking has significant limitations in the solid-state fermentation production of red yeast rice.

[0005] In addition, there are temperature differences between the inside and outside of the fermentation material. Simply tapping and turning it manually cannot mix the fermentation material evenly, which also greatly affects the temperature uniformity and makes it impossible to effectively control the temperature conditions of fermentation production.
