Heat treatment equipment for heating and controlling nematodes parasitic on root crops such as garlic and producing black garlic

摘要

PROBLEM TO BE SOLVED: To provide a heat treatment apparatus in which heat-treatment for eelworm extermination and black garlic production are made possible with one unit.SOLUTION: A circumference of workpieces stacked on a cart is enclosed by a cover 8 for limiting entry of air in a heated heat treatment chamber surrounded by insulation panels. An alignment part of this cover is joined by fasteners to form a cylindrical state. An open port in an upper part of the cover 8 is connected to an air inlet 11. The air in the workpieces surrounded with the cover 8 becomes a flow of rectification sucked from a lower surface and passing to the upper part by operation of a concatenating intake fan 12. A heat treatment apparatus enables heating conditions to be given equally by this airflow passing through all parts of the workpieces. A blind lid is installed to a connection flange 19 of the air inlet 11 and a duct circulation port part as means for sealing the interior of the treatment chamber in the black garlic production. Both treatment is made possible by the correspondence of the above.SELECTED DRAWING: Figure 1
