Description
Technical Field
[0001] This utility model relates to the field of fruit food processing, and in particular to a continuous fruit crushing and pulping machinery and equipment. Background Technology
[0002] Most traditional equipment operates intermittently, requiring shutdown, unloading, cleaning, and refeeding after each crushing and pulping cycle. This results in long production cycles, making it difficult to meet the demands of large-scale industrial production. Furthermore, the design of the crushing components is often flawed, leading to uneven fruit crushing and incomplete separation of pulp and juice, affecting the taste and quality of the final product. For instance, worn blades in some machines fail to completely crush the fruit, resulting in large particles in the pulp. During crushing and pulping, the high temperatures and mechanical friction generated by the equipment damage heat-sensitive nutrients in the fruit, such as vitamin C and anthocyanins, reducing the product's nutritional value. The complex internal structure of the equipment also creates many dead zones, making it difficult to thoroughly remove residual pulp and juice during cleaning, which can easily lead to bacterial growth, affecting food safety. Moreover, the cleaning process is time-consuming and labor-intensive, increasing production costs. Therefore, a continuous fruit crushing and pulping machine was designed. Utility Model Content

[0019] The working principle of this utility model: This device has five main features and functions.
[0020] The first function is multi-stage cutting and crushing, which allows the fruit to be crushed evenly and into smaller particles. This process involves crushing and cutting the fruit separately through two devices: the crushing structure 3 and the pulping and cutting structure 5. During crushing, two toothed structures, a fixed toothed crushing rod 11 and a shaft-mounted toothed crushing rod 12, are used to compress and crush the fruit, turning the whole fruit into small particles and juice. This juice is then fed into the pulping and cutting structure 5 through a valved manifold 4. There, the high-speed cutting blades 17 break the fruit into a pulp.
[0021] Secondly, to enhance continuous operation, this equipment employs two sets of crushing structures 3. During the feeding process, the screw conveyor 1 continuously transports fruit, which takes time to fill to meet the required quantity. The distribution structure 2 can transport fruit to the two sets of crushing structures 3 at different times. Thus, one crushing structure 3 is always working while the other is transporting fruit. When the crushing work inside the crushing structure 3 is completed, because the fruit is in a state of block, granule, and juice mixture, its flowability is poor. It takes a long time for the fruit to flow through the valved manifold 4 to the pulping and cutting structure 5. Inside the pulping and cutting structure 5, under the effect of high-speed cutting and stirring, it is made into a slurry. The flowability of the slurry fruit is better than that of block or granule fruit. It can be discharged faster through the discharge pipe 22. Therefore, there is a waiting period between the feeding and discharge times inside the crushing structure 3. By using two crushing structures 3, rapid and continuous operation can be achieved.
[0022] Thirdly, it has the function of cooling and removing heat. When the high-speed cutting blade 17 is working at high speed, it is inevitable that some heat will be generated. The connected water pipe 18 can be connected to flowing water, which can carry away the heat in the fruit and prevent the fruit from changing its taste due to high temperature.
[0023] Fourthly, it reduces oxidation. This process occurs because the fruit pulp is in a pulpy state during cutting and grinding, and contact with air accelerates the oxidation of the pulp. Therefore, by introducing a protective gas, such as nitrogen, into the protective gas inlet pipe 20, the oxidation of the fruit pulp can be reduced, thus improving the quality of the product.
[0024] Fifthly, the cleaning process involves connecting the rinsing water to the pipe 19, which can be connected to an external water source and cleaning solution. After the pulping and cutting structure 5 has finished its work, the inside of the pulping and cutting structure 5 is cleaned to reduce the presence of pulp. In conjunction with the operation of the high-speed cutting blade 17, the high-speed cutting blade 17 and the side wall of the pulping sealing cylinder 13 can be cleaned, which can effectively reduce problems such as bacterial growth.
[0025] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
