Gas directly-heated type circular drying machine for walnut

Abstract

The invention discloses a gas directly-heated type circular drying machine for walnut. The gas directly-heated type circular drying machine comprises an outer box body, wherein the outer box body is internally provided with an inner box body at intervals, the lower end of the peripheral wall of the inner box body is connected with the bottom surface of the outer box body, and an exhaust chamber is formed between the inner box body and the outer box body; a spherical combustor is arranged on the bottom surface of the outer box body, the spherical combustor is internally provided a combustion furnace, a plurality of radiating pipes communicated with the inner part of the spherical combustor are arranged on the side wall of the lower part of the inner box body, and flow baffle plates which are distributed in the shape of V are arranged in the inner box body above the radiating pipes; and a walnut lifter is vertically arranged on one side wall of the inner box body in the exhaust chamber, the inner box body is internally provided with conveyer belts from top to bottom at intervals, a walnut baffle plate is respectively and slantwise arranged on each of the inner walls of two sides of each conveyer belt, a material outlet end of the lower-end conveyer belt is near to a material inlet of the lifter, a material outlet of the lifter is near to a material inlet end of the upper-end conveyer belt, and an exhaust pipe arranged on the top surface of the inner box body extends out of an air outlet arranged on the top surface of the outer box body. According to the gas directly-heated type circular drying machine, the walnut is dried by hot air generated by the communication of natural gas, and the gas directly-heated type circular drying machine is quick in speed, time-saving, and labor-saving.

Description

technical field [0001] The invention relates to a gas direct heating type walnut circulation dryer. Background technique [0002] 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". Its nutritional value is very high, and it is known as "long live fruit" and "longevity fruit". Walnut has extensive cultivation and edible basis in our 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,...
