Description

Technical Field

[0001] This utility model belongs to the field of agricultural product processing, specifically relating to a crushing device for chia seeds with high crude fat content. Background Technology

[0002] Chia seeds are rich in the essential fatty acid alpha-linolenic acid, various antioxidants (chlorogenic acid, caffeic acid, myricetin, quercetin, kaempferol, etc.), and also contain abundant dietary fiber, protein, vitamins, and minerals. Chia seeds contain approximately 31% fat, classifying them as oilseeds rich in fat. Therefore, grinding chia seeds is a challenging task.

[0003] Existing oilseed crushers generally employ compression crushing, shearing, or impact crushing. However, compression crushing often results in uneven crushing and poor crushing efficiency. It frequently causes the crushed powder to seep out and stick to the rollers due to temperature increases, thus affecting product quality and work efficiency. In shearing or impact crushing, when high-oil material particles are crushed to a certain size, the oil encased in the cell walls is exposed and becomes liquid oil under the heat generated by shearing or impact forces. This liquid oil mixes and adheres to components such as fibers and starch in the material, not only clogging the mesh and sticking to the blades but also leading to low crushing efficiency and even preventing the material from being crushed to the target particle size.

[0004] Currently, cryogenic pulverizers are used for pulverizing materials in plant research. Cryogenic pulverizers add a cold source to cool the materials while pulverizing them, ensuring that the oils remain solid after the cell walls are broken and do not liquefy due to the heat accumulated during shearing or pulverization, thus avoiding the problem of mixing and sticking. However, most existing cryogenic pulverizers use liquid nitrogen as a cold source, so a closed-loop cycle of liquid nitrogen storage, supply and recycling is required. Its structure is complex, the processing cost is high, and it is difficult to use it for general food production.

[0005] Chinese Patent 201810393055.1 discloses a "low-temperature pulverizer for crushing high-oil materials." Its working principle is as follows: the material enters the pulverizing chamber through the feed inlet, where a servo motor drives the rotating wheel to crush the material. The material then falls into a cooling chamber cooled by air, achieving thorough cooling and absorbing the heat generated during high-speed pulverization, thus preventing the oil in the material from melting and affecting its quality. While this document does not solve the problem of high-oil materials sticking to the rotating wheel, it provides inspiration for using common coolants to lower the material temperature. Summary of the Invention

[0006] The purpose of this invention is to provide a device for crushing chia seeds, so as to solve the problem that the heat accumulated during the shearing or grinding process of chia seeds causes liquefaction, mixing and sticking, resulting in low crushing efficiency or even the inability to crush the material.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0008] A chia seed crushing device includes a frame, a frame cover, a hopper, a cooling chamber, a connecting ring, a fixed grinding disc, a movable grinding disc fixing device, a movable grinding disc, and a driven wheel. The frame is cylindrical, with external threads on the upper part of its outer wall. It has 24-48 evenly distributed frame fixing holes, and four evenly distributed support legs at the bottom. The frame cover is circular, with internal threads corresponding to the external threads of the frame on its inner periphery. The frame cover is threaded to the top of the frame. A through hole in the center of the frame cover connects to the hopper. Water inlets and outlets are located on the center lines of both sides of the hopper. A frame cover fixing hole is located at a position corresponding to the frame fixing holes. The top of the frame cover has 6-8 symmetrically distributed fixing bolt holes. The cooling chamber is a hollow cylinder, enclosed by cooling chamber walls on all sides. The central hollow part serves as part of the feed inlet. Sealed water inlets and outlets are located on the top wall of the cooling chamber, corresponding to the water inlet and outlet holes on the frame cover. Six to eight symmetrically distributed holes for fixing bolts (second type) are located on the bottom wall of the cooling chamber, and these fixing bolts are welded into the holes for sealing. The connecting ring is a flat annular structure with holes for fixing bolts (first type) corresponding to the holes on the frame cover. The inner diameter of the connecting ring is the same as the outer diameter of the cooling chamber. The connecting ring is welded to the outer circumference of the cooling chamber with the top plane horizontal. The frame cover and the cooling chamber are movably connected together by the fixing bolts (first type) and the connecting ring. The diameter of the fixed grinding disc is the same as the outer diameter of the cooling chamber. The grinding disc teeth are concave and radial. The center of the fixed grinding disc is hollow, forming a feed inlet together with the hollow part of the cooling chamber. The fixed grinding disc has holes corresponding to 6-8 fixing bolts at the bottom of the cooling chamber. The fixed grinding disc is movably fixed to the bottom of the cooling chamber wall through the fixing bolts, forming an integral part with the frame cover. The moving grinding disc fixing device includes a fixing frame, a connecting shaft, a bearing, a support plate, and fixing bolts. The fixing frame is a horizontal structure, fixed on the center line of the bottom of the frame. The center of the fixing frame has a hole through which the connecting shaft can pass. Bearings are welded to the fixing frame and around the central hole. The top of the connecting shaft is connected to the support plate, which has 6-8 symmetrically distributed fixing bolt holes. The diameter of the moving grinding disc is the same as that of the fixed grinding disc. The grinding disc teeth are concave and radial. The moving grinding disc has holes corresponding to 6-8 fixing bolt holes on the support plate. The moving grinding disc and the support plate are movably fixed together by the fixing bolts. The driven wheel is movably fixed to the bottom of the connecting shaft. The driven wheel is connected to a motor fixed to the frame or the ground via a belt.

[0009] Furthermore, in fixing the frame and frame cover, this invention employs a pin-fixing method. After the frame cover is rotated until its fixing hole aligns with any of the frame fixing holes, the pin-fixing component is inserted. This prevents the frame cover from shifting due to mechanical vibration, ensuring the uniformity of the pulverizing effect. The pin-fixing component has an upper ring and a pointed cylindrical pin-shaped structure at the bottom.

[0010] Furthermore, a receiving plate is provided at the bottom of the frame to facilitate the collection of crushed materials.

[0011] The beneficial effects of this utility model are as follows: (1) The crushing process is completed by a horizontal double grinding disc structure. The horizontal grinding disc structure has a more uniform output and a better crushing effect than the vertical grinding disc structure. (2) A cooling chamber is provided above the fixed grinding disc. The cooling chamber uses water circulation to cool down the crushed oil material, so that the material does not liquefy and stick to the grinding teeth, and the crushing device can operate normally. (3) The gap between the frame cover and the frame is controlled by a threaded method, so that the gap between the fixed and moving grinding discs is more uniform and the adjustment of the gap size is more accurate. (4) A movable pin fixing part is used between the frame and the frame cover to prevent the problem of misalignment of the frame and the frame cover during operation vibration caused by the threaded control of the grinding disc gap, and further ensures the uniformity of the crushing effect. (5) The overall structure is simple, the cost is low, and it is easy to promote and apply. Attached Figure Description
