Full Text The present invention relates to an improved continuous circular cutting device useful for lemon and other similar fruits. The improved machine of the present invention is particularly useful for cutting of lemon and other similar fruits in to four pieces of different geometrical shapes. Geometrical shapes so obtained by using the device of the present invention are of uniform dimension, size and are obtained in a continuous manner. The cut lemon and other similar fruits in to four pieces will have application in pickle and other similar fruit processing industry. The improved machine of the present invention is therefore useful as an improved device for cutting of lemon and other similar fruits in to four pieces. Based on stationery multi edged cutter and a rotating centralizing/locating flats concept, an improved device for cutting of lemon and other similar fruits in to four pieces, untouched by hand is proposed for the first time according to this invention. As an important improved device, different varieties and sizes of lemon and other similar fruits can be cut in to four pieces by using this improved device. Pickle is popular in India and is considered as an important ingredient of the daily meal.
Different types of pickles are produced in the country by different industries in various brands. Lemon, mango, tamarind, tomato are the common types of fruits used in preparing pickles in the country. Presently pickles are produced at cottage industry level, small scale level as well as in large scale by very few industry. Some of the main problems in producing them in cottage scale, small scale, large scale is the tedious operation of cutting the large quantities of fruits to the required shape and size continuously, particularly lemon.
Attempt to produce continuous compact machines for cutting of lemon and other similar fruits in to four pieces, is the first of its kind. The pickle manufacturers are deprived of a suitable machine for lemon cutting and depend on the skill of the operators. Many a times the operators are in the risk of cutting their fingers as well. In case a device is made available for continuous cutting of lemon and other > similar fruits which is one of the ingredients of the pickle, would result in reduction in accident, labor and drudgery on the part of laborers, help in hygienic operations, and enhance uniformity in quality and quantities. Traditionally cutting of lemon and other similar fruits in to four pieces is done by using a sharp knife manually. Most of the production centers are cottage and tiny industries, the processing is done manually there is a scope for accident, non-uniformity in size, cut shape, geometry and unhygienic handling of the fruits. The cutting of lemon and other similar fruits in to four pieces is done carefully for pickle processing industry. In order to overcome these difficulties, if a cost effective machine for cutting of lemon and other similar fruits is made available, it would mechanize large-scale production of different types of pickles by small and cottage scale manufacturers hygienically.
Hitherto the process of cutting of lemon and other similar fruits is based on manual cutting. The operator uses a stainless steel knife for cutting the lemon in to four pieces. The lemon is spread on the cutting table and the operator picks one at a time and cuts them in to four pieces. The knife and the table are to be kept clean during the process of cutting. The cut lemon is transferred in to a stainless steel tray or a vessel for further processing.
The drawbacks of manual cutting of lemon are:
> There is a variation in the size of the cut pieces.
> Manual cutting will lead to non-uniform product sizes.
> The operators cut their fingers, leading to unhygiene.
> The table and the knife are prone for microbial contamination.
> The process is labor intensive and human drudgery is very high.
> The final geometry of the product would depend on the skill of the labor.
In the drawing accompanying this specification, figure 1 represents an embodiment of the continuous circular cutting machine for lemon and other similar fruits, designed and developed at Central Food Technological Research Institute, Mysore against copending patent No. 226043 (313/DEL/02), Dated 26.03.02
The continuous circular cutting machine for lemon and other similar fruits has the following drawbacks.
1. The size variations of the fruit can only be accommodated in only one
direction.
2. The locating /centralizing is done separately for different cuts.
3. Two sets of centralizing discs are needed for cutting the lemon and other
similar fruits in to four pieces.
4. Two sets of knives are needed for cutting the lemon and other similar fruits in
to four pieces.
5. Due to size variations the transfer of the first cut lemon and other similar fruits
in to the second disc is difficult
6. Transferring of the lemon and other similar fruits after the first cut in to the
second centralizing disc with specific orientation is not uniform.
7. The machine cannot be operated by hand incase of electric power failure.
The main object of the present invention is to provide an improved continuous circular cutting device useful for lemon and other similar fruits.
Another object is to provide hygienic conditions through mechanized operation.
Still another object of the present invention is to cut the lemon and other similar fruits in to four pieces in a single stage of operation.
