Abstract

A method for obtaining vegetable oil from tomato seed includes comminuting tomatoes, two-step grating of the tomato pulp for separating the seeds with fine inert matters, pressing the oil. After the pressing the substance obtained is separated two times to isolate the oil from the liquid.

Description

Description of the invention

The invention relates to the processing industry, and the final product can be used in the food, 2 perfumery, pharmaceutical and other industries of the national economy. The invention can be used in the production of vegetable oil from the seeds of tomatoes and other crops without heat treatment.

The existing technology for the production of vegetable oil from tomato seeds has a number of disadvantages, in connection with which this product, which is expensive, is produced in very small quantities |1, 21.

Tomatoes contain 1.2...295 seeds to the weight of the fruit, there are more of them in small ones, and less in large ones |Z, 41. 70 With the modern technology of processing tomatoes and extracting seeds from fruits, their preparation for making vegetable oil from them consists in the following Tomatoes after washing and inspection are crushed, then the crushed mass (pulp) is heated to 70...802C and the heated pulp is rubbed on a rubbing machine with the diameter of the holes of the working sieve in most cases Zmm, while the skin, seeds and other inedible impurities are separated from the pulp ( ballast fabrics). The rubbed pulp is finished on the finisher with the diameter of the holes of the working sieve from 0.4 15 to 0.7 mm. Here, the remains of ballast tissues are removed, and the finished mass - semi-finished tomato is sent for further processing into the final product (tomato juice, tomato puree, tomato paste). The removed waste during wiping is washed with water and sent to the finisher to separate moisture, small skin frequencies and impurities from the seeds (5, b).

The tomato seeds processed in this way are dried in rotating drum dryers with 20 counter current, from one side, the top, the seeds are fed into the drum, and from the second, the bottom, hot air with a temperature of 60...80 "C is fed into the drum. The drum is installed at an angle of 15...307 relative to the horizontal |71.

The frequency of rotation of the drum is two times less than the critical one, and therefore the centrifugal force does not act on the seeds and the seeds gradually move along the drum to meet the flow of hot air.

The length of the drum is 4...5 m. The seed stay in the drum is up to 10 minutes. During this time, free moisture is separated from the seeds 25. A part of the dry skin is separated from the dried seeds by the agegrodynamic method, and the seeds themselves are packed and sent to the kernel oil factories, where oil is made from them using high-pressure presses.

Tomato seeds contain up to 2895 vegetable oil (71.

The main disadvantage of the traditional method of producing vegetable oil from tomato seeds is their double cm 3 heating, washing, finishing - this is a large expenditure of energy resources. A temperature of 70...809C has a negative effect on the quality of the obtained oil - the acid number increases and the oil has a limited shelf life. From an economic point of view, the traditional method of producing oil from tomato seeds brings a loss to the enterprise, and therefore large canneries of Ukraine (Kherson, Odesa, Izmail) refused this production for various reasons. - with A new method of producing vegetable oil from tomato seeds is proposed, which consists in the following: M

Tomatoes, after washing and inspection, are crushed on a knife or other crusher, then without heat treatment, the tomato pulp is rubbed on a rubbing machine with the diameter of the holes of the working sieve of rubbing at least

B5mm. In this operation, coarse particles of the skin and other coarse impurities are separated from the tomato pulp. The pulp rubbed in this way contains tomato tissues, seeds and small particles of the skin. This pulp is directed « 20 to the second rubbing on a working sieve with a hole diameter of 1.5 mm, where the seeds with particles of skin and particles of connecting tissues are separated from the pulp. The pulp after the second wiping machine is sent to finishing and subsequent technological operations. The seeds with impurities removed from the second grinding machine are sent to the extraction process on a high-pressure press, where oil is extracted from the seeds, and vegetable juice and small particles of plant tissue are extracted from the impurities. The resulting liquid-oil suspension with particles of plant tissues is sent for separation, first on a separator-separator, where particles of -1 35 plant tissues are removed from the suspension, and then on a separator separator, where oil is separated from plant juice from a liquid-oil emulsion. The liquid (plant juice) separated on the separator separator contains up to 490 dry substances and is sent to the production of concentrated tomato products. Due to the lack of heat treatment, the new method of boiling and drying seeds is energy-saving, and the obtained oil has a natural quality. 50 Sources of information: (o) 1. Marchuk H.S.
