Description

Technical Field

[0001] This utility model relates to the field of rice bran drying technology, and in particular to a rice bran drying equipment. Background Technology

[0002] Rice bran, also known as brown rice husk, is a byproduct separated during rice processing. Rich in carbon, hydrogen, and oxygen, and containing abundant protein, fat, and vitamins, it is a nutritious byproduct. With the increasing global demand for biofuels, rice bran, due to its high carbon-to-hydrogen ratio and potential for conversion into renewable energy, is gradually becoming an important raw material in the fuel industry. Drying is a key step in improving the efficiency of rice bran utilization, and rice bran drying equipment plays a vital role in enhancing resource utilization efficiency and promoting green industrial development. Through technological innovation and intelligent transformation, future equipment will be more efficient and environmentally friendly, laying the foundation for achieving sustainable development goals.

[0003] A search revealed an existing patent (publication number: CN109247489A) that discloses an infrared food drying container, comprising: a circular container body, an infrared ceramic heating drying lamp, a lamp holder, a temperature controller, and a food tray; a hole is made in the center of the bottom of the circular container body, and the lamp holder is placed in the center, with the infrared ceramic heating drying lamp placed on the lamp holder; the temperature controller is installed on the outside of the circular container body. The infrared food drying container of this invention is simple to manufacture, has low manufacturing cost, is easy to operate, and is convenient to maintain, providing convenience to people's lives and offering them certain benefits.

[0004] However, in actual use, the distances of the top and bottom items from the heat source are different, and the infrared ceramic heating drying lamp is more efficient at drying bottom items than top items. This design may cause several problems. First, the moisture distribution of the material is uneven during the drying process. The bottom items dry too quickly, while the top items may remain at a higher moisture level, resulting in uneven drying. Second, due to the uneven heat distribution, the top items require a longer drying time, leading to an excessively long drying cycle and affecting production efficiency. In addition, product quality may be unstable, with some areas being over-dryed or over-wet, affecting the overall quality of the rice bran. Uneven heat source distribution may also lead to energy waste, with the bottom items being over-dried and the top items under-dried, requiring additional energy and reducing equipment efficiency. Finally, this uneven heat source distribution may increase the burden on the equipment, leading to excessive wear and tear on the heat source components after long-term use and increasing equipment maintenance costs.

[0005] Therefore, this utility model provides a rice bran drying equipment. Utility Model Content

[0006] The purpose of this invention is to solve the problem that in the existing technology, infrared ceramic heating drying lamps are more efficient at drying bottom items but less efficient at drying top items. This design may bring several problems. First, the moisture distribution of the material is uneven during the drying process. The bottom items dry too quickly, while the top items may retain higher humidity, resulting in uneven drying. Therefore, a rice bran drying device is proposed.

[0020] Compared with the prior art, this utility model provides a rice bran drying equipment, which has the following beneficial effects:

[0021] 1. The rice bran drying equipment described in this utility model utilizes a rotating agitator within a storage unit to agitate the stored rice bran raw materials. This agitation mixes the raw materials at the bottom and top, ensuring uniform heating and preventing localized overheating or over-hydration, thus improving drying efficiency and rice bran quality. The agitation also accelerates moisture evaporation, increasing drying efficiency, while preventing rice bran from clumping or piling up, ensuring the raw materials remain loose within the equipment and facilitating air circulation. Uniform heating and drying not only improves the consistency of rice bran quality but also effectively reduces energy waste and enhances overall production efficiency.

[0022] 2. The rice bran drying equipment described in this utility model heats the rice bran by simultaneously introducing hot air into the storage component during agitation. Compared to other heating methods, this significantly improves heat transfer efficiency, accelerates the drying process, and shortens drying time. The uniform distribution of hot air combined with agitation ensures that all parts of the rice bran are heated evenly, avoiding localized overheating or over-humidification and improving the uniformity of the drying effect. At the same time, hot air helps to quickly evaporate the moisture in the rice bran, improving drying efficiency and reducing energy consumption. Furthermore, the combination of hot air and agitation prevents the rice bran from clumping, keeping it loose and ensuring air circulation, further improving the drying effect. Overall, this heating method can utilize energy more efficiently, reduce production costs, and improve the quality of dried rice bran. Attached Figure Description
