Full Text 4. DESCRIPTION
This invention relates to Pusa Fruit Coring Device (Hand Operated) to help in removing cores from apple and Pineapple fruits suitable for use commercially at small scale.
In the known art the crude method used is coring knife which is not efficient and safe. The fruits not only get injured during coring which is uneven but hands also feel fatigue in a 15 minute period of operation. The coring knife can core 250 apples/hr and 150 pine apples/hr
The objective of the invention is to devise a device for obviating the above said defects and to remove core from apple and pineapple fruits in an effective way on small scale. It is also the objective of the invention to have a device that is simple in construction, easy in operation and also available at affordable price to the entrepreneurs.
Thus according to this invention a Pusa Fruit Coring Device (Hand Operated) to be used for removing core from apple and pineapple comprises of a frame, a handle two fruit holders, two coring tools, a core conveyor and a stand.
The frame consists of a 40-mm diameter and 865-mm long mild steel rod vertically mounted in a base plate made from 15-mm thick mild steel plate.
The handle is made of 20-mm diameter and 550 mm long mild steel rod. It can be adjusted to suit the height of the operator. It can be fitted in different convenient positions as per the requirement.
The fruit holder is made of wood. It has 145, 145 and 165 mm length, width and height respectively. It holds the fruit in proper position during coring and removes the cored fruit from coring tool. It can accommodate upto l0-cm long apple and pineapple fruits. It has fruit resting cone at the center. A cone adjustment screw is provided to adjust the fruit-resting cone. The fruit holder is fitted in the frame base plate with the help of four clamps.
The coring tool is the heart of the device. It removes the core of the fruit. It is taper in shape. It is made of 305 mm long stainless steel pipe having 20 mm outer diameter and 0.75 mm thickness for apple and 31 mm outer diameter and 0.75 mm thickness for pine apple fruit.
The core conveyor is made of aluminum sheet revolved section. It is slanted downward at 45 degree. It is 50 mm wide and 130 mm high at head and 45 mm wide 40 mm high at the tail. It conveys the core from coring tool to the core container. It contains 85 mm long and 45 mm wide core pusher and 85 mm high and 50 mm wide an inspection glass window at the head side.
The stand consists of four wooden legs of 175-mm height. The each leg is fitted with leveling screw at the bottom in order to level the device before operation.
Now the invention will be more clearly described with reference to Fig. I of accompanying drawing, which shows the layout diagram of the Pusa Fruit Coring Device (Hand Operated) and Fig.2 shows coring tool and fruit holder for apple and pineapple. Referring to Fig.l the handle (2) & coring tool (3) is mounted on frame rod (1) while fruit holder (4) is mounted on top and stand (7) on bottom of base plate (6). The fruit resting cone (5) is fitted with fruit holding assembly. The core pusher (9) and inspection window glass (10) is fitted with core conveyor (11). Working of the Invention:
First of all the fruit is placed on the fruit holder in vertical orientation in a proper position. The coring tool is moved down and up with the help of handle. During this process the coring tool removes the core of the fruit which mainly consists of seed and other inedible portion. The cored fruit is removed and fruit is kept on the fruit holder. The coring tool is again moved down and up. In every downward movement of coring tool the core moves up till it reaches the top of the coring tool. The core can be seen through the glass window. The core is pushed down by core pusher in the core conveyor, which conveys it to the core collection container.
Advantages:
The Pusa Fruit Coring Device (Hand Operated) is simple in construction and easy in operation. The fruit is not injured during coring. The handle is adjustable as per the height of the operator. The leveling screws can level the device. The operator does not feel much fatigue in continuous one-hour operation, the device can remove cores from more number of fruits as compared to traditional coring knife.
