Description

Raw and Ripe Coffee Separator

technical field

The utility model relates to coffee processing equipment, in particular to a raw and ripe coffee fruit separator for rapidly separating raw and ripe coffee fruits.

Background technique

At present, coffee picking is divided into mechanical picking and manual picking. Mechanical picking is suitable for coffee gardens with flat land and large-scale planting. The advantage is that the cost is low and the efficiency is high. Poor and inconvenient to separate; while manual picking is selective picking, usually at intervals of 8-10 days, walking between the trees several times and only picking those ripe red berries. The advantage is that the coffee berries after picking The size is uniform, the maturity is relatively close, the impurity contained is less than that of mechanical picking, and the proportion of mixed fruits is small, which is beneficial to the later processing. The disadvantage is that the cost is high and the work efficiency is low. Generally, it is only used for high-quality coffee. .

At present, manual picking is still the main method in China. After the picking is completed, it is still necessary to manually separate the raw and ripe fruits, which is labor-intensive and inefficient.

Contents of the invention

What the utility model aims to solve is the problem that after the existing coffee cherries are picked, it is necessary to manually separate the raw and ripe berries, which results in low efficiency and high work intensity. Fruit separator.

The raw and ripe coffee fruit separator of the utility model is characterized in that the separator includes a casing, a rotating shaft, a feed hopper and a discharge port, the feed hopper is installed on the upper part of the casing, and the discharge port is arranged at one end of the lower part of the casing. The rotating shaft is fixed at the central position inside the casing, and the lower half of the casing is covered with sieve holes to facilitate the discharge of coffee beans and ground coffee pulp from the sieve holes.

The rotating shaft is provided with a feeder and an agitator, the feeder is installed on the rotating shaft below the feed hopper, and the agitator is installed on the rotating shaft between the feeder and the discharge port, when the rotating shaft rotates, it drives the agitator accelerator The rotation speed of the coffee cherry inside the shell makes the coffee cherry be squeezed and crushed quickly.

The feeder is a helical blade, which is beneficial to quickly transport the coffee fruit to the outlet.

There are six agitators in the shape of "Π", which are respectively vertically fixed on the rotating shaft, and two adjacent agitators are arranged in a staggered manner.

The discharge port is provided with a pressure door, and an L-shaped handle is fixed on the pressure door. The horizontal end of the handle is installed on the upper part of the discharge port and rotates around the connection between the handle and the discharge port. The level of the pressure door and the handle is There is a gravity block on the vertical end of the handle. When the pressure on the lower part of the pressure door is greater than the pressure on the upper part of the pressure door given by the gravity block, the pressure door will drive the handle to rotate upwards, and the discharge port will open. Improve the extrusion effect of materials inside the casing and improve the grinding effect.

The lower part of the discharge port is provided with a discharge trough, which is convenient for discharging waste materials such as fruits out of the separator.

The gravity block is provided with fastening screws, and the gravity block is fixed on the handle by fastening screws, and the position of the gravity block on the handle can be adjusted to adjust the pressurized force received by the coffee fruit inside the casing.

Pour the mixed raw and ripe coffee cherries directly into the feeding hopper, turn on the motor to drive the rotating shaft to rotate, the mixed raw and cooked coffee cherries are squeezed and ground each other under the action of the rotating shaft, and the peel of the ripe fruit is quickly crushed and passed through The sieve hole on the casing falls, and the fruit is squeezed at the discharge port, and the fruit continues to increase. When the pressure it gives to the pressure door is greater than the pressure given by the gravity block, the pressure door opens and the excess fruit is discharged. After some fruits are discharged through the discharge chute, the pressure door is automatically closed to maintain the extrusion and friction inside the casing, so that the ripe fruits are crushed faster.

The raw and ripe coffee fruit separator of the utility model has simple structure, scientific design, and is convenient to use. It utilizes the difference in softness and hardness of the pericarp between the raw fruit and the ripe fruit, and uses the raw fruit to crush the pericarp of the ripe fruit to expose the ripe fruit. Coffee beans no longer need to be manually separated one by one, which speeds up the separation and effectively improves production efficiency.

Detailed ways

Embodiment 1: A machine for separating raw and ripe coffee fruits, including a casing 1, a rotating shaft 2, a feed hopper 3 and a discharge port 4, the feed hopper 3 is installed on the top of the casing 1, and the discharge port 4 is arranged on the casing At one end of the lower part of 1, the rotating shaft 2 is fixed at the central position inside the casing 1, and the lower half of the casing 1 is covered with sieve holes to facilitate the discharge of coffee beans and ground coffee pulp from the sieve holes. The rotating shaft 2 is provided with a feeder 5 and an agitator 6, the feeder 5 is installed on the rotating shaft 2 below the feed hopper 3, the agitator 6 is installed on the rotating shaft 2 between the feeder 5 and the discharge port 4, and the rotating shaft 2 When rotating, the agitator 6 is driven to accelerate the rotation speed of the coffee fruit inside the casing 1, so that the coffee fruit is quickly squeezed and crushed. The feeder 5 is a helical blade 11, which is conducive to quickly conveying the coffee fruit to the direction of the discharge port 4. There are six stirrers 6 in the shape of "Π", which are respectively vertically fixed on the rotating shaft 2, and two adjacent stirrers 6 are arranged in a staggered manner.
