FIELD OF INVENTION
The present invention relates to a Tamarind De-seeder Machine. More particularly the invention relates to separation of seeds from tamarind berries by the machine in high capacity in less time and fatigue.
BACKGROUND OF THE INVENTION
Separating seeds from tamarind berries is a time consuming and tedious job. This equipment aims to solve that problem. It can be operated by one person and has a capacity of about 60 kg per hour with 80 percent separation efficiency. So far, traditionally hand-driven knife used to do the job manually or using hand-cutter material. The seed is exposed by the application of force by hand with the help of a hand tool.
OBJECT OF THE INVENTION
Therefore it is an object of the invention to propose a tamarind de-seeder machine which is capable of de-seeding in high volume in less time eliminating the tediousness and fatigue experienced in the prior art.
BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
Tamarind is fed through a hopper (7) installed on top part of the equipment (M). A cylindrical de-seeder drum (5) with specially designed depressions (9) allows the separation of seeds from tamarind. The de-seeder has a concave which allows the easy collection and separation of the tamarind pulp. It is a pedal driven (1) equipment and reduces substantially the drudgery involved and promises good operating conditions with safer ergonomics. The machine consists of a drum (5) which is operated by the pedal (1). It contains a plurality of depressions around the periphery. Tamarind is fed into the hopper and is placed in the depressions on the drum while the drum rotates. It contains a plurality of depressions (9) on the drum (5) while the drum rotates. The concave surface which is fixed on the frame presses on tamarind berry and expose the seeds. The pulp is scrapped initially followed by scratching of the skin of the seeds on the surface by the concave. The seeds separate. Pulp come out through the perforations on the concave. Seeds are knocked down by a set of pegs which rotate on a separate drum at the exit end and fall on the ground. Tamarind pulp and seeds are collected in separate containers at the bottom.
Tamarind de-seeding exposes the seed while the drum (5) is rotating. It is fitted with a shaft (4). The de-seeder has a concave (11) which allows easy collection and separation of the tamarind pulp. It has dimension according to shaft and is made of various materials like mild steel being commonly available. Drum (5) is

connected with a shaft and supported by a flywheel (6) to maintain the speed. It is a rotating device and attach with hopper shaft with a key. The main components of the machine are
a) Pedal: (1) It is a foot driven device and used to operate the machine.
b) Pedal-rod: (2) It is a connecting rod between pinion-gear and pedal to transfer the power from pedal to pinion.
c) Pinion-gear: (3) Pinion-gears are connected with the shaft and used to rotate the drum through the shaft which is connected to the pinion.
d) Shaft: (4) It is used to transfer the power to connected components like drum, flywheel etc.
e) Drum: (5) A cylindrical de-seeder drum with specially designed depressions allows the separation of seeds from tamarind.
f) Concave: (11) It is fixed to the frame and wraps around the drum for 225°. It is perforated with closely spaced circular holes of diameter 8 mm. It is supported at one end by a hinge and the other end by a spring (10) which helps to adjust the clearance between the drum (5) and concave automatically.

g) Knock out pegs: These are mounted on the exit end side of the concave. It is used to knock out the seeds from the depressions. It is a set of pegs mounted on a rotating shaft.
h) Flywheel: (6) The wheel is used to maintain the power speed in this machine.
i) Hopper: (7) Tamarind is fed through a hopper installed on top of the equipment.
j) Frame: (8) Frame is construction of angle iron material. Frame is maintaining the overall components of machine with standby.
This equipment can be operated by one person and has a capacity of about 60 KG per hour with 80 percent separation efficiency.
Presently, the tamarind deseeding is conducted in one step while exposing is carried out in another step. Inertia of flywheel (6) is responsible for maintaining the speed required for exposing the seed from tamarind by the drum (5). The person also sometimes changes situation in between two steps. The operator has a better working.
Tamarind de-seeder machine (M) with pedal (1) operated drive is capable of rotating at the speed required for shaft (4) and has a drum (5), not available in

market, for exposing. The production rate of this operation per person is be higher than in the traditional method.
Tamarind de-seeder machine operated by leg drive pedal at a comfortable situation. It has pinion (3) and wheel (6) to maintain the speed generated by pedaling and transfers the power to drum (5) through a shaft (4). The working situation is ergonomically safer than the traditional method and conductive to higher lever of productivity.

WE CLAIM
1. A tamarind De-seeder machine (M) comprising;
a frame (8) for constructing the machine;
a pedal (1) for operating the machine;
a pedal rod (2) for connecting the pedal (1) with pinion-gear (3) mounted on a shaft (4) for transferring the power from pedal (1) to the pinion-gears (3);
a shaft (4) having a pinion at one end and a fly wheel (6) at the other end fixed to it;
a drum (5) attached to a hopper shaft with a key and having depression (9) for separation of seeds from tamarind;
a plurality of depressions (9) disposed on the periphery of drum (5);
a concave (11) fixed to the frame (8) supported at one end by a hinge and the other end by a spring (10);
a plurality of knock out pegs mounted on the exit end side of the concave and rotating on a separate drum;
a hopper (7) installed on top of the machine (M) for feeding tamarind; Characterized in that,

The pedal (1) is disposed for pressing and generating a motion to be transferred to the pedal rod (2) and then to the pinion gear for transferring the motion to the shaft (4) for rotating the fly wheel (6) and the drum (5) wherein the hopper (7) is disposed for being fed with tamarind, the said tamarind being placed in the depressions (9) on the rotating drum (5) while the concave surface (11) is fixed on the frame for pressing tamarind berry for exposing the seeds when the set of pegs rotating on a separate drum are disposed for knocking down the seeds for collection.
