BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to improvements in machinery for cleaning roots and husks of mung and soya beansprouts.
2. Description of the Background
The lack of good quality sprouts (without roots and husks) has been a problem for cooking dishes. Not only does it cause the appearance of untidiness in the dish, but it also causes the natural taste of the vegetable to diminish.
There have been some proposals to clean the sprouts with machinery, but these have proven ineffective. The percentage of the by-products (roots, husks) along with the sprouts was just as high after cleaning with this machine as for sprouts which had not gone through the machine. For example, one previous machine included a group of devices for beating and pushing the sprouts within a container of water followed by the addition of a suction machine to vacuum the floating by-products.
These proposals have the disadvantage of removing limited roots, while still leaving a number of husks and roots along with the sprouts. Another disadvantage of these processes is that many sprouts become broken from the action of the machinery. In the end, the quality of the sprouts is not as high as it should be. Even though the consumers may remove the by-products, the problem of the broken sprouts still remains.
SUMMARY OF THE INVENTION
These problems are overcome by the present invention which provides a machine for cleaning roots and husks from beansprouts comprising a non-elastic rotation cylinder inside a casing cylinder.
The rotating cylinder is adapted to break only the roots of the beansprouts and at the same time to separate the by-products from the sprouts.
In one form of the invention, the machine for separating beansprouts from roots and husks comprises a perforated rotating cylinder inside a casing.
The spinning motion of the rotating cylinder enables the by-products to become separated from the products by travelling through the perforated holes and into the gap between the rotating cylinder and the casing.
In another form of the invention the rotating cylinder includes two spiral strips internally and externally attached so that as the rotating cylinder rotates, the spirals will travel in opposite directions to one another. The spirals are shaped so that once screening takes place due to the rotating cylinder's rotation, the by-products are screened through the perforated holes and then transported within the gap between the rotating cylinders and the casing in the direction of the loading inlet.
In this instance the external spiral acts as a pushing device for transporting the by-products out of the machine.
As the unprocessed sprouts are loaded continuously, a direct horizontal force is exerted, enabling the rotating sprouts to be transported from one end to the other as products are separated from by-products through the continual rotating screening process.
The internal spiral assists only in the guiding of the products from one end to the other and is not a necessity to the transportation of the sprouts.
BRIEF DESCRIPTION OF THE DRAWINGS
To assist with understanding the invention, reference will now be made to the accompanying drawings which show one example of the invention. In the drawings,
FIG. 1. shows one example of a beansprouts, roots and husks cleaning machine according to this invention; and
FIG. 2. shows the application of such a beansprouts, roots and husks cleaning machine in operation.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Throughout the rotating cylinder perforated holes form a screening mechanism which enables the separation of the husks and roots from the sprouts during the rotating cycle. It is essential that the range in diameter of the perforated holes lie between 5.00 mm to 12.70 mm only, allowing only roots and husks to travel through the perforated holes while leaving the sprouts within the rotating cylinder. Outside this range either the roots and husks may not get through the perforated holes or more of the unprocessed sprouts than desired will get
