Abstract

The invention provides a method for removing soil and impurities from fresh yellow ginger. The method comprises the following steps of: (1) firstly feeding the fresh yellow ginger to a rotating cage, and spraying water flow by two stages to the surface of the yellow ginger by a pressurizing spraying head so as to uniformly clean the yellow ginger; (2) removing smaller-grained sludge in the fresh yellow ginger during the rotating cage cleaning process, pumping the sludge to a sludge drying pool by a sludge pump after the separated sludge settles to a catchment pool with a cone bottom, and conveying the cleaned yellow ginger to a flotation tank under the rotation of the rotating cage; (3) conveying the yellow ginger to the flotation tank holding 20-40% calcium chloride solution or 5-25% sodium chloride solution to remove most of large-grained sludge and stones, and simultaneously further removing fine soil and impurities; (4) feeding the yellow ginger suspended on the surface of a flotation agent into a vibration screen through the overflow port of the flotation tank, cleaning the flotation agent on the surface of the yellow ginger, and conveying the cleaned yellow ginger to a disintegrator by the vibration screen; and (5) discharging the flotation agent in the flotation tank to a recovering tank, and cleaning and transporting the large-grained sludge and stones settled at the bottom of the flotation tank by adopting an artificial cleaning method. By adopting the treating process, the soil and impurities in the fresh yellow ginger can be effectively removed, particularly large-grained stones and irony impurities.

Description

technical field

[0001] The invention relates to a method for removing soil and impurities in fresh turmeric. Background technique

[0002] The fresh turmeric purchased by general enterprises contains 5% to 30% of mud, sand and stones, and occasionally iron nails, iron wires, nuts, etc. (collectively referred to as dirt). Blocking the equipment space, reducing the processing capacity of the equipment, and affecting normal production, so it must be removed and cleaned. At present, the methods for cleaning turmeric are generally tumbler cleaning and manual cleaning. The tumbler cleaning method can remove most of the fine-grained mud and sand in the turmeric, but the larger-grained stones enter the crushing process with the turmeric because they cannot pass through the mesh holes of the tumbler. The manual cleaning method is very labor-intensive, low in efficiency, and the removal effect of soil impurities is not ideal. The traditional ginger washing method cannot solve the p...
