Embodiment Construction

[0033] The present invention will be further described with reference to the accompanying drawings.

[0034] refer to figure 1 , figure 2 , which is a nut surface treatment process disclosed in this embodiment, includes the following steps:

[0035] a. Preliminary cleaning: Clean the nut with a washing machine to remove iron filings and sundries on the surface of the nut.

[0036] b. Deep cleaning: Put the cleaned nuts into the caustic soda solution for deep cleaning 1-3 times, and then put them into the hydrochloric acid solution for deep cleaning.

[0037] c. Liquid removal treatment: transport the cleaned nuts to the liquid removal device 1, and the liquid removal device 1 removes the liquid on the nuts.

[0038] d. Drying: Put the nuts into the drying device for drying.

[0039] e. Spraying and curing: Spray the dried nuts, put the sprayed nuts into a curing box for curing, and then get the finished nuts.

[0040] refer to figure 2 The liquid removal device 1 inclu...

Abstract

The invention discloses a nut surface treatment process, which relates to the technical field of nut production process. The key points of the technical scheme include: a. preliminary cleaning; b. deep cleaning; c. liquid removal treatment: transporting the cleaned nut to the liquid removal process The liquid removal device includes an organic base, a feed hopper arranged on the base and feeding nuts, and a dehumidification channel arranged on the base and located at the lower end of the feed hopper; the dehumidification channel includes an outlet with the feed hopper The upper connection port corresponding to the feed port, the lower connection port for the nut to discharge the dehumidification channel, and the curved passage between the upper connection port and the lower connection port, the inner wall of the curved passage is provided with a cotton cloth layer; d, drying; e , Spray curing. The invention removes water after the nut is cleaned, shortens the drying time and improves the drying efficiency.

Description

technical field [0001] The present invention relates to the technical field of nut production technology, more specifically, it relates to a kind of nut surface treatment technology. Background technique [0002] The basic production process of nuts includes steel stamping, steel stamping, tapping (thread processing), heat treatment (generally higher-grade nuts need heat treatment, low-grade nuts do not need heat treatment process), surface treatment. [0003] In the prior art, a Chinese patent document whose application publication number is CN109317386A discloses a treatment process for the surface of nuts, which includes the following steps: a. Preliminary cleaning: the nuts are cleaned by a washing machine to remove iron filings and Sundries; b, deep cleaning: put the cleaned nut into the caustic soda solution with a mass concentration of 0.3-0.4%, and clean it deeply for 1-3 times at a temperature of 30-40°C; then put it into a mass concentration of In 0.5-0.7% hydroch...
