Description

Technical Field

[0001] The utility model relates to the technical field of raisin processing, in particular to a raisin dehydration and air drying machine. Background Art

[0002] Raisins are a food made by dehydrating grapes with the help of solar heat or artificial heating. They are high in sugar and are typical high-energy nutritional products. Raisins have low water content and are easy to transport and store. The most important dried grapes in the world are the green seedless grape variety Seedless White. Other dried varieties include White Rose and Black Corinth. However, due to climatic reasons, some areas in my country cannot produce raisins by natural air drying. Therefore, this type of raisin dehydration air drying machine plays a very important role in the production of raisins.

[0003] In view of this, Chinese patent number CN104013081B proposes a raisin dehydration and air-drying machine, which greatly improves the dehydration effect and efficiency of raisins, and the raisins are almost intact and shiny after dehydration. The cost is low and it is easy to operate, which is worthy of promotion. However, during the use of the above technical scheme and the existing raisin dehydration equipment, the raisins are placed inside the equipment, and the steps of draining, air-drying and dehydration are required. The grapes cannot be moved in the corresponding steps and are easily piled up and squeezed. In addition, the existing air-drying machine does not have a drainage function before the grapes are dehydrated, which easily causes a large amount of water vapor to be generated during the hot air drying process, directly causing some grapes to rot, affecting the production volume and air-drying efficiency of the raisins. In this regard, the present design scheme proposes a raisin dehydration and air-drying machine. Utility Model Content

When the raisins are poured in, the baffle 206 is rotated vertically to block them on the second support frame 207, and the air outlet slot of the bellows 209 faces the second support frame 207 to blow air and drain water from the grapes. After dehydration is completed, the sealing cover 11 is opened, and the first support frame 204 is taken out to collect the air-dried raisins.

After the baffle 206 is rotated to open the dehydration tank 201, the electric telescopic rod 303 is started to be telescoped on the connecting rod 302, so that the connecting rod 302 is stretched and then the second support frame 207 is rotated and tilted in the dehydration tank 201, and the raisins will naturally roll to the upper side of the first support frame 204;

[0025] Furthermore, a drainage groove 4 is provided at the bottom of the inner wall of the dehydration tank 201 below the second support frame 207, a motor 5 is fixedly provided on one side of the dehydration box 1, and one end of the baffle 206 is fixedly connected to the output end of the motor 5, and a plurality of air inlet grooves 6 are provided at equal distances on both sides of the outer wall of the dehydration box 1, and one end of the inner wall of the dehydration tank 201 is located below the second support frame 207 and is designed to be in an inclined state, so that the drained water flows into the drainage groove 4 through the inclined interior, and is then discharged by the second drain pipe 8 on one side, and the air inlet groove 6 plays a role of air intake when the hot air blower 202 is started;

[0026] Furthermore, a first drain pipe 7 is inserted through one end of one side of the outer wall of the dehydration box 1, and the inner wall of the first drain pipe 7 is communicated with the inner wall of the dehydration tank 201, and a second drain pipe 8 is inserted through the other end of one side of the outer wall of the dehydration box 1, and the inner wall of the second drain pipe 8 is communicated with the inner wall of the drainage tank 4, and the second drain pipe 8 discharges part of the water vapor and liquid during the process of the hot air blower 202 drying the raisins;

A bellows 209 with an induced draft fan 210 is arranged above the second support frame 207 to speed up the drainage of the grapes. After the drainage is completed, the baffle 206 is rotated to open one end of the dehydration tank 201, and then the lifting mechanism 3 is used to lift the second support frame 207. One end is rotated and tilted in the dehydration tank 201 to pour the drained raisins into the first support frame 204 and evenly distribute them. At this time, the sealing cover 11 seals the dehydration tank 201, and the raisins cannot leave the dehydration tank 201. The hot air blowers 202 on both sides are started for hot air drying. After a period of time, the raisins can be air-dried and dehydrated, and part of the water vapor is directly discharged through the exhaust groove 9 at the upper end. It is not easy for water vapor to remain in the dehydration tank 201 to cause the grapes to rot. At the same time, the grapes can be moved to the area corresponding to the air-drying step in the dehydration box 1 in a targeted manner without manual adjustment by the staff. While increasing the production of raisins, the air-drying efficiency of the device is also improved.
