Description

Circulating microwave electric heating combined walnut dryer

technical field

The utility model relates to a circulation type microwave electric heating combined walnut dryer.

Background technique

Walnuts, deciduous trees, are native to the Near East, also known as walnuts, Qiang peaches, and almonds, cashews, and hazelnuts, and are known as the world-renowned "four major dried fruits". It can be eaten raw, stir-fried, oil-extracted, prepared into cakes, candies, etc. It is not only delicious, but also has high nutritional value. It is known as "Longevity Fruit" and "Longevity Fruit". Walnuts originate in China and have extensive cultivation and edible bases in my country. In recent years, with the adjustment of Xinjiang's agricultural industry structure, the planting area of forestry and fruit industry has expanded rapidly, and the output of walnut has developed rapidly, which has brought a huge impact on Xinjiang's economic and social development. At present, walnut has become one of the pillar industries of characteristic fruit in the southern Xinjiang production area, and plays an important role in promoting the adjustment of Xinjiang's agricultural structure, increasing farmers' income, and promoting export earnings. At present, walnuts in Xinjiang are still mainly dried in the sun. This method is often affected by the natural climate, which requires a long drying time, high labor intensity, and unstable product quality. It is easy to cause walnut kernels to rot and deteriorate. have a huge impact. This is not in harmony with the development of modern precision agriculture. From the perspective of the development of high-end precision agriculture, the overall level of walnut drying machinery and drying equipment needs to be improved.

Contents of the invention

The purpose of the utility model is to provide a circulating microwave electric heating combined walnut dryer, which can quickly and efficiently dry walnuts, has a simple structure, saves energy, is easy to control, and has high working efficiency.

The purpose of this utility model is achieved in this way. A circulating microwave electric heating combined walnut dryer includes a box body, a walnut lifter is vertically arranged on the side wall of the box body, and the box body is horizontally installed from top to bottom. Along the conveyor belt, walnut baffles are installed on the inner walls on both sides of the conveyor belt. The discharge end of the lower conveyor belt is close to the feed port of the lifter, and the discharge port of the lifter is close to the feed end of the upper conveyor belt. An exhaust pipe and a microwave emitting device are installed on the top surface of the box body, and an electric heating tube is horizontally arranged on the bottom surface of the box body.

The drying process of the circulating microwave electric heating combined with walnut dryer adopts clean and efficient combined heating of microwave and electric heating. The microwave mainly heats and dries from the inside of the walnut to make the water move outward quickly, and the electric heating mainly heats and dries the walnut from the outside to the inside. The combination of the two can quickly and efficiently dry walnuts, and at the same time avoid the damage to the internal quality of walnuts by single microwave heating.

The drying process is as follows: walnuts fall into the conveyor belt from the inlet and outlet doors, move forward under the drive of the conveyor belt, fall into the next level of conveyor belt through the baffle plate, and finally fall into the lower left of the box after being transported one by one. The lifter at the bottom lifts the hopper, is driven by the vertical lifter to the top, and falls into the conveyor belt through the deflector to continue the cycle; when the walnuts circulate, the microwave emission device on the upper part of the box and the electric heating device at the bottom of the box start to match each other. The walnuts are heated and dried; the circular movement of the walnuts in the box improves the uniformity of heating, and improves the speed and efficiency of drying. The dried walnuts are output from the inlet and outlet doors through the rotating deflector. The utility model can quickly and efficiently dry walnuts, has a simple structure, saves energy, is easy to control, and has high working efficiency.
