The invention discloses a
processing and production technology for
impurity removal and blending of white tea. A
production line device comprising a grading
assembly, a
winnowing impurity removal
assembly, a uniform stacking and blending
assembly and a weighing and packaging assembly is adopted for carrying out
impurity removal and blending. The production technology comprises the following steps that Q1, white tea is subjected to
metal foreign matter adsorption treatment and
electrostatic adsorption; Q2, the white tea is conveyed to a
winnowing feeding inclined conveying unit through an inclined
bucket elevator and a plane conveyor; Q3, a double-row
winnowing machine selects out and discharges sand and stone
foreign matter and grass and hair
foreign matter in the white tea; Q4, a foreign matter picking and removing procedure is carried out; Q5, a magnetic grading procedure is carried out; Q6, a uniform stacking and blending procedure is carried out; Q7, a conveying and lifting procedure is carried out; Q8, a weighing procedure is carried out; Q9, a boxing procedure is carried out; and Q10, a packaging procedure is carried out. The
automatic control technique of automatic feeding, automatic impurity removal, automatic blending, automatic weighing, automatic boxing and automatic packaging is applied, the production efficiency is effectively improved, the product quality is improved, and continuous and automatic refining
processing of white tea is successfully achieved.
