Cold-pressed vegetable oils

For many generations valuable cold-pressed oils have been extracted from high-fat oilseeds and kernels, and have been used for preparing meals and as remedies.Since several years - in the face of increasing ecological damage and of limited mineral oil ressources - these oils are also used in the field of technology.

A variety of seeds can be used for oil production. Excellent sorts are rape, sunflower, flax, hemp, sesame, borage, evening primrose, thistle, poppy and black cumin. And also soja, almonds, hazelnuts, walnuts, grape seed, mustard, saphlor, rhizinus, kukani nuts, palm kernels, jatropha, etc.

COLD PRESSING – THE SOFTEST METHOD OF OIL EXTRACTION

The cold-pressing process does not require complicated machinery. The characteristics of this process are low energy requirement without any use of chemical extractive agents. The oil extracted in a cold-pressing process retains its healthy ingredients – vitamines, enzymes, lecithin, trace elements.

EXTRACTION OF OIL IS EASY

The construction of our endless screw presses is based on years of experience in construc-tion and application in the field of cold-pressing of oilseeds. These oil extraction machi-nes are in continuous operation and do not require any special supervision.

We offer machines in various sizes: from small presses for personal use and for direct sel-lers up to big processing capacities for oil mills, producer communities, forage producers, store houses and co-operatives.

RAPEThe brown-black rapeseeds are growing in a pod which is 5-10 cm long. The oil content of rape is 40-45 %. Seed yields per hectare: approx. 3-5 tons.

FLAXFlax is a blue-blooming plant which grows in almost all European coun-tries. Oil content: approx. 30-48 %, seeds yield per hectare: approx. 0.6-2.8 tons.

THISTLEOil is extracted from the seeds of the safflower. Oil contents: approx. 43-58 %.

HEMPOil is extracted from the ripe seeds of the hemp plant, which reaches a height of 2-4 metres. The oil con-tent is approx. 28-35 %, seeds yield per hectare: up to 1.6 tons.

SuNFLOwERThe bright yellow flowers con-stantly turn towards the sun. Oil content approx. 26-72 %, seeds yield per hectare: approx. 2-3 tons.

Requirements of the seeds

Quality assurance by careful storage and treatment

CLEANING OF THE SEED

Following the harvest, and prior to storage, the seed is being cleaned. Impurities, like metal pieces, sand or stones should be removed for reasons of product quality as well as to avoid damages to the endless screw press.

DRYING OF THE SEED

The humidity of the seed has to be reduced to approx. 6-8 %. This ultimate humidity is the precondition for the storage of the seed for several months, and especially for the

subsequent optimal pressing of the seed.STORAGE OF THE SEED

The preconditions for an optimal storage of the seed are a high degree of ripeness and low degrees of humidity and impurities. Cool storage temperatures with sufficient air and heat exchange are essential.

Use of cold-pressed vegetable oilsThe multitude of possible applications makes the oil extraction with the cold-pressing method a lucrative source of income for your company.

COLD-PRESSED OIL

Compared with all other extraction methods, oil produced by cold pressing has decisive advantages: the ingredients (eg. vitamines, lecithin, enzymes, flavours, trace elements) are almost completely preserved. It has a stronger taste and a higher proportion of polyunsaturated fats. As only one pressing takes place, the expenditure of energy and machinery is low.

EDIBLE OILS

Nutritionists today have great demands on edible oils which can be recommended for a balanced diet. The content of unsaturated fats (linoleic and linolenic acid) should be as high as possible. In the case of rapeseed oil this amount is 94 grams per 100 grams of oil. Compared with other oils, this is top-quality. Cold-pressed rapeseed oil distinguishes itself by its nutlike taste and an intense yellow colour. It will keep for about six months and should not be heated up.

REMEDIES AND COSMETICS

The polyunsaturated fats cause a variety of biologically positive effects and have there-fore proved to be of therapeutic value. As carriers of liposoluble vitamines they have sub-stantial influence on blood circulation, skin, immune system and metabolic processes. Cold-pressed vegetable oils are also used in the production of cosmetics - soaps, creams and other products of beauty culture.

FuEL

Its energy density is only slightly (3-7 %) lower than that of diesel oil. It is an eco-friendly fuel for special motors suitable for the use of vegetable oil (eg. block-type thermal power stations, aggregates) or for vehicles with adapted fuel system (eg. private cars). It is not to be confused with „Bio-Diesel“ or rape methyl ester. One hectare of land planted with rape yields approximately 1.100 litres of oil. Assuming a consumption of 8 litres per 100 km, one hectare of land makes it possible to drive 14.000 km by car.

FORAGE OIL

The high energy content makes it possible to improve low-energy forage. Rapeseed oil, for example, covers the need of essential fatty acids, supports the provision of liposolub-le vitamines, has a dust-binding effect and improves the flowability of pelleted forage mixtures.

EDIBLE OILSCold-pressed edible oils - an inte-gral part of a healthy diet

FuELRapeseed oil - fuel for vehicles with a slight adaption of the motor.

Use of the press cake

The press cake which is obtained by cold pressing contains more residual oil and has therefore a higher value for animal food purposes than the one which is obtained by warm pressing or oil production by normal extraction.

According to the law of animal foods the following press cakes are suitable for animal feeding: Rape, flax, sunflower, safflower. One hectare of land planted with rape yields an average amount of rape cake of approx. 2000 kg.

Presently a large part of the concentrated fodder for animals is being imported from countries outside the EU in the form of grinded soybeans. This can partly be replaced by rape expellers.

Apart from that the press cake is suitable as solid fuel for chaff furnaces, for the pro-duction of biogas and as a compost-fertilizer. Small amounts can also be used as baking additive and in the production of cosmetics. The highest value, however, can be obtained in using the press cake as animal fodder.

Everything from one companyKarl Strähle GmbH & Co. KG offers the optimal solution for every need

Our machines fulfil the special demands on quality, capacity, user-friendliness and main-tenance. We attach special importance to solid construction, high-quality components made in Germany, spheroidal graphite iron for the strainer baskets and brand articles for motors, gears and clutches.

To minimize wear and tear we use highly stable, hardened special steel. To ensure an easier installation our machines consist of several structural components. This is also an advantage when the machines have to be installed in hardly accessible buildings. Another very important task for us is to offer an excellent aftersales-service for our customers.

It goes without saying that our services include information and advice before and after the installation and initial operation of our presses and machines.

Small presses:SK 60/1 and SK 60/2Due to the technical equipment of the SK 60/1 an extension to a twin press is possible at any time. Thus the seed throughput per hour can be doubled. The twin press SK 60/2 is able to process different seeds at the same time. Thus you are flexible, and you save time and efforts for setup and cleaning.

During the whole flow of the seed through the press the oil is drained via the strainer which surrounds the pressing space.

Our endless screw presses work without any heating of the seeds and the machinery. The press screw, or its segments, are cone shaped. Thus the volume of the pressing tunnel is reduced, in order to increase the pressure on the material.

Oil filtration

DESCRIPTION OF PARTLY AuTOMATED

FILTRATION SYSTEM

The oil is circulating between the raw oil tank and the chamber filter press. Every time the oil passes the filter plates, a layer of filter cake is beein built at the filter cloths.Once the plates are completely filled with cake, the circulation is stopped. Now the oil passes through the fine filtration and flows into the clean oil tank.
