Description

Technical Field

[0001] The utility model relates to the technical field of egg product drying, in particular to a tunnel-type skin-salt egg product drying machine. Background Art

[0002] The main raw material of salted egg products is fresh duck eggs. After the pickling production is completed, they are inspected and selected in the inspection workshop and then boiled. After the eggs are sterilized in a high-temperature water bath, they need to be dried. After the boiled eggs are dried, they enter the packaging system for packaging.

[0003] The dryers purchased by small and medium-sized factories are generally economical and simple. They primarily dry eggs by blowing hot air from above during transportation. However, in actual production, considering the blind spots and dead angles of egg transportation, this direct overhead blowing method has a narrow and uneven drying range, low drying efficiency, and low utilization of hot air. It can also cause incomplete drying, leaving residual water stains on the eggshell surface, which is not conducive to storage. Therefore, it is necessary to improve on the existing equipment, and a tunnel-type salted and peeled egg product dryer is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a tunnel-type salted and peeled egg product dryer, which is used to improve the existing dryers used in small and medium-sized factory workshops and improve the drying performance and effect.

[0006] Preferably, the heat-insulating box body includes a top cover, side box panels and a box bottom plate, and the top cover, side box panels and box bottom plate form a box body.

[0007] Preferably, transparent covers are respectively provided at both ends of the top cover, and a curtain is provided at the bottom of the transparent cover.

[0008] Preferably, a heat conducting net is provided on the side of the electric heating tube close to the air distribution tube in the hot air box.
