Preserved-fruit sulphuring method and preserved-fruit sulphuring device

Abstract

The invention provides a preserved-fruit sulphuring method and a preserved-fruit sulphuring device. The device comprises a sealed cabinet. N layers of parallel smoke distribution pipes with rectangular cross sections are arranged in the cabinet from top to bottom. One end of each smoke distribution pipe is sealed, and the other end of each smoke distribution pipe extends out of the cabinet to be connected with the smoke output end of an external sulphuring smoke sucking pump. A carrying drawer is arranged between every two adjacent layers of the smoke distribution pipes. Base plates of the carrying drawers are parallel to smoke distribution surfaces of the smoke distribution pipes. Grid holes are distributed in the base plates of the carrying drawers evenly. The diameters of the grid holes are smaller than the diameters of to-be-processed preserved fruits. Sides, facing the drawers, of the smoke distribution pipes at the top layer and the bottom layer in the cabinet are the smoke distribution surfaces. Both the upper side and the lower side of each smoke distribution pipe between the smoke distribution pipe at the top layer and the smoke distribution pipe at the bottom layer are the smoke distribution surfaces. Smoke distribution holes are distributed evenly in the smoke distribution surfaces of the smoke distribution pipes, and other surfaces are sealed. By the device, sulphur smoke is evenly distributed on each layer in the cabinet, so that sulphuring degrees of the preserved fruits are uniform, and color non-uniformity of the preserved fruits due to local sulphuring non-uniformity is avoided.

Description

technical field [0001] The invention relates to the field of candied fruit production, in particular to a method and device for sulfur fumigation of candied fruit. Background technique [0002] There is a vulcanization process in the production process of candied fruit. Vulcanization has the following functions: ①keep the bright color of candied fruit; ②improve the preservation rate of nutrients such as vitamin C in candied fruit; ③accelerate the penetration of sugar and shorten the time of candied sugar. The existing sulfur fumigation method is usually to put the candied fruit on the drawer, put the drawer together with the ignited sulfur in a large vat or cement pool, and cover it with a quilt for sulfur fumigation. This method of sulfur fumigation does not deal with the flow of sulfur smoke, and when there are many candied fruit particles, it is easy to stack. It is difficult to ensure uniform sulfur fumigation of candied fruit particles by using the traditional sulfur fu...

Problems solved by technology

This method of sulfur fumigation does not deal with the flow of sulfur fume, and when there are many candied fruit particles, it is easy to stack. It is difficult to ensure that the candied fruit particles are evenly sulfurized by using the traditional sulfur fumigation method.
