Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, and in particular to a small-scale mushroom drying system. Background Technology
[0002] In the current agricultural industry and food processing sector, the preservation and processing of mushrooms is a crucial step. With the increasing demand for healthy food, the market size for mushrooms, as a nutritious and uniquely flavorful ingredient, is expanding daily.
[0003] Traditionally, mushroom drying relies heavily on natural sun-drying. However, this method has many drawbacks. On the one hand, natural sun-drying is severely constrained by weather conditions. In rainy weather, mushrooms are prone to mold and spoilage, resulting in significant losses of raw materials and making it impossible to meet stable production and supply demands. On the other hand, the sun-drying process is time-consuming, requires a large area, and is difficult to keep clean, as impurities and dust can easily get mixed in, affecting the quality of the mushrooms.
[0004] With the advancement of industrialization, some large-scale mushroom drying equipment has emerged. However, these large-scale equipment are often designed for large-scale production scenarios, with high investment costs, requiring dedicated sites, and consuming a lot of energy. For small farmers, individual operators, and some small food processing workshops, they cannot afford the high initial equipment purchase costs, and the subsequent operating costs also deter them.
[0005] In addition, there are many types of mushrooms, and different varieties of mushrooms vary significantly in size, moisture content, heat sensitivity and other characteristics. Existing large-scale drying equipment lacks flexible parameter control functions when handling small batches and multiple varieties of mushrooms, making it difficult to accurately adapt to the best drying process for various small mushrooms. As a result, the color, taste and nutrient retention of the dried mushrooms are not satisfactory.
[0006] Therefore, developing a low-cost, easy-to-operate, energy-saving, and environmentally friendly system that can accurately meet the drying needs of small-scale mushrooms has become an urgent need for the development of the mushroom industry. This system can help small-scale practitioners increase the added value of their products and better adapt to market competition. Utility Model Content
[0007] In view of the technical problems existing in the background art, this utility model provides a small mushroom drying system.

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0029] like Figures 1-6As shown, a small-scale mushroom drying system includes a drying box 1, a first partition plate 7, a ventilation and heating mechanism 2, and a dehumidification mechanism 4. The drying box 1 is a rectangular cavity structure with one end open, and the interior of the drying box 1 is divided into chamber A and chamber B by the first partition plate 7. Several L-shaped stainless steel strips 8 and stainless steel mesh trays 9 are provided on chamber A and chamber B. An air guide groove is provided on the other end of the drying box 1, and the ventilation and heating mechanism 2 is provided in the air guide groove. The ventilation and heating mechanism 2 includes a second partition plate 201, an electric heating finned tube 202, a silent fan 203, and a spiral air inlet 204. The air guide groove is divided into chamber C and chamber D by the second partition plate 201, and both chamber C and chamber D are provided with electric heating finned tubes 202 and silent fans 203. A sealing baffle is provided on the air guide groove, and a spiral air inlet 204 is provided on the sealing baffle.
[0030] It should be noted that, in order to dry the mushrooms, we have installed a first partition plate 7 inside the drying box 1 to divide it into chamber A and chamber B. In addition, L-shaped stainless steel strips 8 and stainless steel mesh trays 9 are installed in both chambers. Both chambers can perform drying operations. Moreover, the drying box 1 adopts a sandwich structure and has an air guide chamber inside, which is connected to the dehumidification mechanism 4 to discharge the moisture generated during drying.
[0031] It should be further explained that during the drying process, airflow needs to be introduced into the chamber, and the air guide channel is divided into chamber C and chamber D by the second isolation plate 201. Both chambers are equipped with electric heating finned tubes 202 and silent fans 203. The air is heated by the electric heating finned tubes 202, and the heated air is guided by the silent fans 203 to introduce the generated hot airflow into chambers A and B.
[0032] It should be further explained that chambers C and D are respectively set up to correspond to chambers A and B, and can be independently controlled and independently introduced with hot air, thus achieving separate operation. This design has the advantage of two main aspects: First, the left and right chambers can be flexibly selected to operate simultaneously or individually according to actual production needs. When the mushroom yield is low, only one chamber is used to avoid energy waste; while during the harvest season, both chambers are operated simultaneously, significantly increasing drying capacity. Second, when processing different types of mushrooms with different moisture levels or maturity, this independent control mode ensures that each batch of mushrooms receives the most precise drying treatment. For example, freshly picked wood ear mushrooms with high moisture content are placed in the left chamber, where rapid heating and precise humidity control quickly remove a large amount of moisture; while the right chamber can simultaneously process oyster mushrooms that have undergone preliminary drying and have slightly lower moisture content, operating precisely according to the oyster mushroom's unique drying curve, without affecting each other, maximizing the drying quality of each type of mushroom.
[0033] like Figures 1-4As shown, the drying oven 1 has a sandwich structure, and a dehumidification mechanism 4 is provided on the inner wall of the sandwich of the drying oven 1; the dehumidification mechanism 4 includes a corrugated dehumidification port 401 and a dehumidification regulating port 402. The corrugated dehumidification port 401 is provided on the sandwich of the drying oven 1, and the dehumidification regulating port 402 is provided on the outer wall of the drying oven 1 and communicates with the inner cavity of the sandwich; a dehumidification regulating cover is provided on the dehumidification regulating port 402.
[0034] It should be noted that the dehumidification system consists of a corrugated dehumidification port 401 located on the inner wall of the interlayer and a dehumidification regulator 402 located at the lower end of the outer wall of the interlayer. During dehumidification, the moisture passes through the corrugated port 401 through the interlayer channel between the inner and outer walls of the box, and is finally discharged through the dehumidification regulator 402 at the lower end of the outer wall of the interlayer. The amount of moisture discharged can be adjusted by rotating the dehumidification regulator cover.
[0035] It should be further explained that the internal air duct design is scientific and reasonable. Through the evenly distributed air outlets, hot air circulates in the drying chamber, ensuring that each layer of mushroom trays receives an equal amount of hot air. This advantage remains significant even when the left and right chambers are independently controlled and operated. The air duct of each chamber has been individually optimized to ensure that the hot air in each chamber is evenly distributed, avoiding local overheating or uneven drying. This ensures that the mushrooms in different chambers are dried to a consistent degree, with uniform color and taste, thus improving product quality.
[0036] like Figures 1-6 As shown, stainless steel water trays 10 are provided at the bottom of both chamber A and chamber B; a first cabinet door 13 and a second cabinet door 17 are provided at the opening of the drying oven 1, and double-layer heat-insulating glass 14 and handles 15 are provided on both the first cabinet door 13 and the second cabinet door 17; a magnetic strip 16 is provided at the opening of the drying oven 1.
[0037] It should be noted that both chamber A and chamber B are equipped with a first cabinet door 13 and a second cabinet door 17, which can be closed during drying. The use of two cabinet doors facilitates individual operation.
[0038] like Figures 1-6 As shown, a control system mounting slot is provided on one side of the drying oven 1, and a control system 5 is installed inside the control system mounting slot. A heat insulation layer is provided on the inner wall of the control system mounting slot, and a heat dissipation hole 12 is provided on the upper part of the control system mounting slot. Several casters 6 are provided at the bottom of the drying oven 1.
[0039] It's worth noting that the system is equipped with an intelligent control panel, making it simple and convenient to operate. Growers only need to set drying parameters, such as temperature, time, and humidity, with a single click, and the system will run automatically, monitoring the drying process in real time and adjusting automatically according to preset programs. Even more impressively, when the independent drying control function for the left and right chambers is enabled, the control panel can precisely control each chamber separately. Users can independently set corresponding process parameters based on the types of mushrooms placed in different chambers, without interference. Some high-end models also support remote control, allowing users to monitor the drying status anytime, anywhere via a mobile app, greatly improving the convenience of production management.
[0040] Drying operation of this system:
[0041] When drying shiitake mushrooms, it is advisable to dry them at a temperature between 50℃ to ensure that their unique flavor and nutrients are preserved to the greatest extent. This avoids the mushrooms from burning and losing nutrients due to excessively high temperatures, or from being incompletely dried and becoming moldy and spoiled due to excessively low temperatures. Moreover, the system can also set different process curves for different dried materials, which is a highly professional and sophisticated function.
[0042] When drying wood ear mushrooms, their moisture content is relatively high. In the initial heating stage, the system will raise the temperature to about 45℃ at a relatively fast rate, causing the surface moisture to evaporate quickly. This process lasts for about 1.5 hours. Then, it enters a constant temperature stage of 52℃, which lasts for about 3.5 hours, to ensure that the internal moisture seeps out steadily and to avoid the wood ear mushrooms shrinking and deforming due to large temperature fluctuations. Finally, in the cooling stage, it is slowly lowered to room temperature, making the texture of the wood ear mushrooms more compact.
[0043] Secondly, when drying oyster mushrooms, since their gills are quite fine, the initial temperature should be raised to 37℃ and maintained for 2.5 hours to gently remove surface moisture. Then, dry them at a constant temperature of 47℃ for 4.5 hours to ensure that the moisture between the gills is completely dried. The cooling process should also be smooth to ensure the integrity and taste of the oyster mushrooms.
[0044] Finally, when drying enoki mushrooms, the temperature is first raised to 32.5℃, then dried gently with a low airflow for 1.5 hours, and then gradually raised to 42.5℃ and maintained for 3.5 hours. The airflow and temperature are precisely controlled to ensure that the whole mushroom is dried evenly and has a bright color. Through this process curve tailored to different types of mushrooms, the drying quality is guaranteed to the greatest extent.
[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
