The construction of the press has a very important role in ensuring accuracy of the oil amount to remain in cake and the capacity. The design, material and life of worms and collar, cage bars and scraper are critical. In addition to this, the engine, reducer, belt-pulley, press main shaft, bearings and body, through which the power of the compression process is obtained, has been developed as a result of the most advanced technology and engineering studies and has been made to meet the needs best.

THE DISTINGUISHING PROPERTIES OF HUM OIL SCREW PRESSES

• PLANETARY REDUCER, the planet reducer with silent operation, ensuring eternal life and high productivity, with low oil consumption, operating with cooled oil circulation by oil cooler; press and cooker reducers are planetary reducers in compact volume, which guarantee the most efficient, the most silent and vibration-free operation. With the reducers, which are the most critical element of power transmission system, productivity is improved by maintenance and failure free eternal life. Reducers are flange coupled to the press body and provide direct power transmission. It is a reducer of the most advanced technology, resistant to extreme conditions.

• WORM AND COLLAR, Worms and Collars made of special alloy, strengthened by means of heat treatment or customs manufactured with armor as an alternative;
  Worms and Collars are designed to get the highest yield from the press. They are made of the materials with the longest life time, and subjected to special treatment. Surfaces have high hardness values thus long life is ensured.

• FREQUENCY CONTROLLED FEEDING SCREW, The feeding screw of which revolution is frequency controlled, ensuring maximum feeding depending on the property of the material; revolution of the feeding screw is adjusted frequency controlled and thus maximum capacity operation of the press is ensured. Feeding screw is driven by a reducer motor.

• THE MAIN SHAFT The shaft, which is cooled by permanent water circulation, ensures the best productivity. The main shaft of the press is equipped with a cooling system with stainless steel piping and special packing to ensure permanent cold water circulation.

• HYDRAULIC CAGE OPENER, when cage is to be opened and closed, it opens and closes the cages very easily with the help of a strong telescopic piston and electric hydraulic power unit without feeling any difficulty and spending much time.

• CAKE BREAKER (optional) is mounted on the press outlet section and it is designed to break the cake into smaller pieces, therefore it provides convenience for the transportation and capacity. Moreover, it helps the extractor work more efficiently and provides uniform size for the cake pieces.

The eqiupment consist of unique welding process, multi-layer hard facing, pure alloy on the final surface, high abrasion and corrosion resistance. The wear parts of screw presses (worms, collars, cage bars) are under the guarantee of HUM for 18 months in operation time. HUM collaborates with “T-1 Ada” company, which is specialized in corrosion and abrasion resistance spare parts manufacturing.

• Milling out from one piece – very strong structure

• Welding (hard facing) by robot in furnace under high temperature

• 4-5 mm hard layer by side

• Unique welding process, multi-layer hard facing, pure alloy on the final surface, high abrasion and corrosion resistance

• Grinded and polished final surfaces

• With threaded holes (easy disassembly)

• Sealing groove (viton or stainless steel rings) to save the main shaft

Oil seeds must be cooked in cooker beforehand in order to improve oil productivity and to evaluate cake better. Humidity, which is released by the gradually increasing temperature, is removed from the vents. With the adjustment of seed temperature in the cooker, optimum seed properties, which must be attained before and after pressing, are obtained. In practice, cooker diameter, heating surface, steam pressure and blending rate is determined based on press capacity.

Cooker Brochure

• 35 to 1.500 ton/day crushed/flaked oilseed inlet capacity.

• HUM Cooker is designed for cooking and/or conditioning oilseeds before pressing or flaking.

• Good mixing ability, low consumption load thanks to special designed and strong agitator arms.

• Assembled delivery, simple and easy installation on site

• CE certificate from the world\'s best accredited organizations.

• Optimum steam consumption thanks to temperature control and level control via PLC

CHANGES AFFECTING OIL PRODUCTIVITY WITH COOKING;

• Flow of oil is easier because oil, of which seed structure is disorderly, is combined in clusters with the influence of heat

• Viscosity of oil is reduced and its extraction from seed becomes easier.

• The protein in the seed is clogged with the influence of water and heat and the seed tissue gains a structure that easily releases oil

• Water surrounding oil clusters is removed with the dehumidifying

• Because humidity level of seed drops to around 3,5-4%, the useful capacity of the press is increased

THE PROPERTIES THAT MAKE HUM COOKER EXCLUSIVE;

• BEVEL HELICAL GEARBOX, long life and high productivity

• AGITATOR ARMS, Arms end parts are designed to prevent the cores from accumulating on the edges of the cooker trays. The arms are machined at an angle of 35 degrees with the cooker surface and are designed so that they do not leave oil seeds on the cooker base and do not deform the cooker steam tray surfaces. AGITATOR ARMS combined with a strong construction in two parts.

• DEHUMIDIFIER, a system with dehumidifier chimney, connected to each cell of the cooker by adjustable flaps, through stainless steel ventilation fan.

• STEAM TRAY, cooker steam trays bottom and top sheets are joined by seamless pipe.

• WELDING TEST, Pressure test and penetrant-radiographic-ultrasound welding test made by specialists pursuant to the regulations about pressurized vessels on cooker steam tray welds.

The CE certificate received from the accredited organizations of the World.

It is necessary to use the HUM Oil Screening Tank to reduce the sediment ratio in the oil to a certain level before it is sent to the decanter or metallic filter to filter the pre-existing sediment.

The screen allows the residue to be removed from the oil by means of specially profiled stainless steel wedge wire screens and thrown out.

These specially profiled wire screens are placed above the oil level and fixed. The residue, which accumulates in the bottom of the prismatic oil tank, is collected on the screen with pellet scrapers.

FEATURES

WEDGE WIRE SCREEN

Wedge wire screen applications provide an optimum screen area due to the thin geometry and small head width. Due to the large profile heights, the profiled wires have a particularly high rigidity and therefore a long service life. The cone of the profile provides a little transresistance, which at the same time prevents large blockage. For these reasons and for many years of experience, we would like to emphasize that screens are particularly suitable for applying sedimented oil filtration. Wire screens are made of stainless steel, different wire profiles and different wire spacings can be used for different requirements.

CONVENIENT LAYOUT

In some embodiments, the inlet, oil outlet, overflow, gear motor unit and channel positions can be changed to match the mill location. For operator’s safety, the tanks are supplied fully enclosed to protect the quality of the oil and prevent the spread of vapors.

TROUBLE-FREE OPERATION

With self-cleaning wedge screen, the oil drains efficiently and there is no need to clean screen regularly. A small number of moving parts, simple proven chain and scraper design guarantees trouble-free operation. Larger tanks have longer drainage times to allow for larger amounts of sediment.

EASY MAINTENANCE

The tanks were designed from the beginning to provide good access for maintenance. Depending on the location of the mill, a man hole is placed in a convenient position.

STURDY DESIGN

The scraper system is equipped with features such as a double spring chain tensioning system to make the chain last longer.

RESIDUE DISCHARGE CONVEYOR

A screw press section with a stainless wire screen is placed on the residue discharge conveyor to recover the oil remaining in the residue at a higher rate.
