Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drying equipment, and specifically relates to a drying equipment for food processing. Background Technology
[0002] In the food processing industry, drying is a crucial step, playing an irreplaceable role in extending shelf life, improving taste and quality, and facilitating subsequent processing and storage. Currently, widely used food drying equipment primarily employs the method of placing food on trays within a drying chamber. Specifically, this type of equipment typically features multiple trays within the drying chamber. The food to be dried is placed on each tray, and hot air is then introduced into the chamber. Through heat exchange between the hot air and the food, the moisture in the food evaporates and is expelled from the drying chamber, thus achieving the purpose of drying.
[0003] However, existing food drying equipment faces several problems in practical applications. When different types of food are placed on each tray, their unique components and aromas cause cross-contamination of flavors within the relatively enclosed space of the drying chamber during the drying process. This cross-contamination not only alters the original flavor and quality of the food, reducing consumer acceptance, but also potentially impacts food safety, such as causing chemical reactions in certain food components that produce harmful substances.
[0004] Furthermore, during the drying process, the steam evaporated from the lower layer of food rises. Because the airflow environment inside the drying chamber is not entirely uniform or stable, this upward-flowing steam is prone to adhesion, especially when it encounters the upper layer of food, where the steam may partially or completely adhere to the surface. This steam adhesion not only increases the humidity on the surface of the upper food, prolonging its drying time and reducing drying efficiency, but may also lead to excessively high local moisture content in the upper food, affecting its drying effect and final quality. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a drying device for food processing to solve the problem of cross-contamination of flavors during food drying, while reducing the impact of steam adhesion on the drying effect and efficiency.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A drying device for food processing includes a drying oven. The drying oven has several partitions that divide the interior into multiple independent drying chambers. Each drying chamber has a door on one side. Guide strips are provided on the inner walls of both sides of the drying chamber, and tray assemblies are mounted on the guide strips. Each tray assembly includes a placement tray with a perforated tray inside. Several first hot air ducts are provided on one side of the drying oven, and several second hot air ducts are provided on the other side. Both the first and second hot air ducts are connected to a hot air blower, and each of the first and second hot air ducts has several first air outlets. A guide plate is provided at the lower part of the partitions, and the guide plate is inclined towards the rear of the drying oven. A water collection trough is provided on one side of the guide plate, and a drain pipe is provided on one side of the drying oven. One end of the water collection trough is connected to the drain pipe.
[0008] Furthermore, the first air outlet on the first hot air duct and the first air outlet on the second hot air duct are arranged alternately, so that the hot air forms a circulating convection in the drying chamber.
[0009] Furthermore, the cross-section of the guide plate has a wave-shaped structure.
[0010] Furthermore, the water collection tank is arranged at an angle, and the height of the side closer to the drain pipe is lower than the height of the side farther from the drain pipe.
[0011] Furthermore, the placement tray is provided with side air holes on both sides, the side air holes being lower than the bottom of the hollow tray, and the first hot air pipe and the second hot air pipe are provided with several second air outlets, the second air outlets being aligned with the side air holes.
[0012] Furthermore, a swing mechanism is provided on one side of the drying oven. The swing mechanism includes a protective cover, a motor is provided at the upper end of the protective cover, a rotating shaft is connected to the output shaft of the motor, a plurality of cams are provided on the rotating shaft, a plurality of through grooves are provided on the side wall of the drying oven, and the cams are located inside the through grooves; a first fixing plate is provided on the partition plate, a second fixing plate is provided at the lower part of the placement tray, and the first fixing plate and the second fixing plate are connected by a spring.
[0013] Furthermore, the placement tray is equipped with a slag collection tray, which is located at the bottom of the hollowed-out tray.
[0014] Furthermore, the inner walls on both sides of the placement tray are provided with spring pieces, the cross-section of which is "n" shaped.
[0015] The beneficial effects of this utility model are:
[0016] 1) This utility model uses partitions to divide the drying oven into multiple independent drying chambers. Each drying chamber dries the food inside it separately, avoiding the problem of cross-contamination of flavors when different foods are dried. In addition, the partitions prevent steam in the lower drying chamber from diffusing to the upper layer, thus preventing steam from adhering to the food in the upper layer.
[0017] 2) The first air outlet on the first hot air pipe and the first air outlet on the second hot air pipe are arranged alternately, so that the hot air forms a circulating convection in the drying chamber, making the temperature and humidity distribution in the drying chamber more uniform, which helps to improve the drying quality and efficiency of food and avoids local overheating or overhumidification.
[0018] 3) The protective cover has a wavy cross-section, which not only increases the surface area of the protective cover and enhances the water vapor capture effect, but also makes it easier to collect the water vapor into the water collection tank.
[0019] 4) A second air outlet is set on the first and second hot air pipes to dry the bottom of the perforated tray. This allows the hot air to not only dry the food from above and around, but also to directly act on the bottom of the perforated tray, achieving multi-directional hot air coverage of the food, reducing dead corners in the drying process, and improving the efficiency of food drying.
[0020] 5) By setting up a swing mechanism, the hollowed-out tray swings back and forth in the drying chamber, and the video inside the hollowed-out tray is flipped in real time, which improves the uniformity and overall quality of food drying, while shortening the time required for food drying and improving drying efficiency.
[0021] 6) A residue collection tray is installed at the bottom of the placement tray to collect the residue that falls during the food turning process, which facilitates the centralized cleaning of food residue and simplifies the cleaning process of the drying oven. Attached Figure Description

[0031] The following will be combined with the appendix Figures 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0032] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0033] like Figures 1-3 As shown, a drying device for food processing includes a drying chamber 1. The drying chamber 1 has several partitions 11 inside, dividing the interior into multiple independent drying chambers. Each drying chamber has a door 12 on one side. Figure 3 As shown, guide strips 17 are provided on the inner walls of both sides of the drying chamber, and tray assemblies 2 are provided on the guide strips 17, such as... Figure 5 As shown, the tray assembly 2 includes a placement tray 21, and the placement tray 21 has a perforated tray 23 inside, where food is placed; as Figure 7As shown, the drying chamber 1 has several first hot air pipes 14 on one side and several second hot air pipes 15 on the other side. Both the first and second hot air pipes 14 and 15 are connected to a hot air blower (not shown in the figure). Each of the first and second hot air pipes 14 and 15 has several first air outlets 141. This double-sided hot air pipe design allows hot air to be evenly blown from both sides of the drying chamber onto the food in the perforated tray 23. Compared to the traditional single-sided hot air drying method, this equipment allows food to reach the ideal dryness level in a shorter time, reducing drying time. Each drying chamber dries the food inside separately, avoiding cross-contamination of flavors between different foods. For example, when drying meat and fruit simultaneously, because they are in independent drying chambers, the meaty smell of the meat will not affect the sweet aroma of the fruit, thus ensuring the unique taste and flavor of each food. Furthermore, this not only achieves the independence of the drying chambers but also provides steam isolation. During the drying process, the steam evaporated from the food rises within the drying chamber. The partition 11 prevents steam from diffusing upwards from the lower drying chamber, thus avoiding steam adhering to the upper food layer. For example... Figure 4 As shown, the lower part of the partition 11 is provided with a guide plate 19, which is arranged inclined towards the rear of the drying chamber 1, as shown. Figure 6 As shown, a water collection trough 191 is provided on one side of the guide plate 19, such as... Figure 3 As shown, a drain pipe 16 is provided on one side of the drying chamber 1, and one end of the water collection tank 191 is connected to the drain pipe 16. When the steam evaporated from the food rises, it is captured by the guide plate 19 and guided into the water collection tank 191. It is then discharged to the outside of the drying chamber 1 in a timely manner through the drain pipe 16, which improves the efficiency of food drying.
[0034] like Figure 7 As shown, the first air outlet 141 on the first hot air duct 14 and the first air outlet 141 on the second hot air duct 15 are arranged alternately, so that the hot air forms a circulating convection in the drying chamber. This convection method can make the temperature and humidity distribution in the drying chamber more uniform, which helps to improve the drying quality and efficiency of food and avoids local overheating or overhumidification.
[0035] like Figure 6 As shown, the cross-section of the guide plate 19 is a wave-shaped structure, which not only increases the surface area of the guide plate 19 and enhances the water vapor capture effect, but also facilitates the collection of the captured water vapor into the water collection tank 191.
[0036] like Figure 7 As shown, the water collection tank 191 is arranged at an angle, and the height of the side closer to the drain pipe 16 is lower than the height of the side farther from the drain pipe 16, which facilitates the rapid discharge of water.
[0037] like Figure 7As shown, the placement tray 21 has side air holes 22 on both sides, which are lower than the bottom of the hollow tray 23. The first hot air pipe 14 and the second hot air pipe 15 are provided with several second air outlets 142, which are aligned with the side air holes 22. The hot air blown out of the second air outlets 142 blows into the interior of the placement tray 21 and dries the bottom of the hollow tray 23. This allows the hot air to not only dry the food from above and around, but also to directly act on the bottom of the hollow tray 23, achieving multi-directional hot air coverage of the food, reducing dead corners in the drying process, and improving the efficiency of food drying.
[0038] like Figure 4 As shown, a swing mechanism 3 is provided on one side of the drying oven 1. The swing mechanism 3 includes a protective cover 18. A motor 31 is provided on the upper end of the protective cover 18. A rotating shaft 32 is connected to the output shaft of the motor 31. A plurality of cams 33 are provided on the rotating shaft 32. A plurality of through grooves 34 are provided on the side wall of the drying oven 1. The cams 33 are located inside the through grooves 34. A first fixing plate 13 is provided on the partition 11. A second fixing plate 25 is provided at the lower part of the placement tray 21. The first fixing plate 13 and the second fixing plate 25 are connected by a spring 26.
[0039] Motor 31 drives shaft 32 to rotate cam 33. Cam 33 moves within slot 34 on the side wall of drying chamber 1, cooperating with spring 26 to connect first fixed plate 13 and second fixed plate 25, causing placement tray 21 to swing back and forth within guide bar 17. This swinging motion can turn the food in the perforated tray 23 in real time, ensuring that all parts of the food are evenly exposed to hot air, avoiding localized overheating or insufficient drying, improving the uniformity and overall quality of food drying, while shortening the drying time and increasing drying efficiency.
[0040] like Figure 5 As shown, the placement tray 21 is equipped with a slag collection tray 24, which is located at the lower part of the hollow tray 23. When the hollow tray 23 swings, the food residue generated during the turning process falls into the slag collection tray 24, which facilitates the centralized cleaning of food residue and simplifies the cleaning process of the drying oven 1.
[0041] like Figure 8 As shown, spring pieces 27 are provided on the inner walls of both sides of the placement plate 21. The cross-section of the spring piece 27 is "n" shaped. The spring piece 27 forms a stable clamping force on the slag collection plate 24, ensuring the firmness of the slag collection plate 24 in the placement plate 21 and preventing the slag collection plate 24 from being thrown out when the placement plate 21 swings.
[0042] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
