Stone removing machine for roasted coffee beans

Abstract

The invention discloses a stone removing machine for roasted coffee beans. The stone removing machine for roasted coffee beans comprises a bracket, a bean cabin, a charge pipe and a hopper. The bean cabin which is fixed on the bracket comprises a cylindrical cabin and a revered cone-shaped cabin; a metal screen is arranged on the upper portion of the cylindrical cabin, a top cover is arranged on the top of the cylindrical cabin, and a draught fan connector connected to an exhaust fan is formed in the top cover; a discharge mechanism is arranged on the lower portion of the reversed cone-shaped cabin, a rotary connector is arranged between the reversed cone-shaped cabin and the discharge mechanism, and the rotary connector and the draught fan connector are arranged in two different directions vertical to the direction of the charge pipe in an opposite manner; the discharge mechanism comprises a discharge pipe and a discharge valve, and the discharge pipe is obliquely arranged at the lower end of the rotary connector outward relative to the center of the cylindrical cabin; the charge pipe is vertically arranged on one side of the bean cabin, and the upper port of the charge pipe communicates with the upper portion of the cylindrical cabin, and the upper portion of the charge pipe is located below the metal screen; the hopper is arranged at the lower end of the charge pipe, and a soil and stone collecting screen is arranged in the hopper. The stone removing machine for roasted coffee beans disclosed by the invention has the beneficial effects that the stone removing machine for roasted coffee beans is simple in structure, low in production cost, good in stone removing effect, high in efficiency and simple to operate.

Description

technical field [0001] The invention relates to the technical field of destoners, in particular to a destoner for cooked coffee beans with simple structure, low production cost, good destoner effect, high efficiency and simple operation. Background technique [0002] The stone removal machine commonly used in daily life is mainly used to remove objects other than very dense materials, such as grains, wheat, etc. to remove granular impurities such as metals and stones. It is often used to separate heavier particles from food grains and other dry granular materials. materials. [0003] Usually, the stone removal machine is mainly composed of feeding suction device, storage hopper, suction hood, sieve body, eccentric transmission, shaking mechanism, frame and other parts. It is to place the raw material on the inclined screen and vibrate up and down. The larger stones, metals, etc. jump higher after being shaken, thus forming an upward movement, and the grain grains with a sm...

Problems solved by technology

The disadvantages of this stone removal machine are: complex structure, low stone removal efficiency, high cost and high price, and its price is about RMB 60,000-120,000

[0004] As for coffee beans, because the processed coffee beans usually contain some granular impurities such as stones, they need to be destoned and graded. However, the existing destoners have complex structures, high costs, and low efficiency. Unable to promote app
