HUM OIL PRESSING (HPRS)
HUM OIL PRESS; it is designed to produce oil and cake, by extracting oil by pressing oil seeds in the worms of the press after they are conditioned at cooker. According to the entry conditions of the next extraction unit, required amount of oil is left in cake. The construction of the press has a very important role in ensuring accuracy of the oil amount to remain in cake and the capacity.
HUM Press consists of a continuous, helical thread that revolves within a stationary, perforated cylinder. As the shaft turns, there is a reduction in volume that results in pressure in the pressing section. The extracted oil flows through the slots distributed over the barrel circumference. The foots-laden extracted oil collected in the oil pan is delivered to the HUM Oil Foots Separator (HFSP). Oil cake leaves the HUM Press through an adjustable conical annular cross-section and is then delivered to the HUM Cake Cooler (HCCL)
Design, material and life time of the cage bars, scraper bars and worms is very critical. Also, the motor, belt-drum, reducer, press main shaft, bearings and the body, where the pressing power is transmitted, have been developed to meet the demand in the best manner using the most advanced technology and engineering. The importance of research-development is ever increasing in today’s economy, where competition at the highest level is being experienced. Firms are could only survive by attaining and using the technological developments in the shortest time.
HUM Oil Cold Presses (HCPR) is designed for single-finish pressing without seed preheating, or for pressing at low temperatures. HUM Oil Cold Press (HCPR) processes removed hulls in HUM Dehulling (HDHL) that has been crushed in HUM Crushing (HCRC) according to its type, as well as uncrushed feedstock.
HUM Oil Finish Presses (HFPR) are designed for single-finish pressing without following HUM Extraction (HEXT) the finish press processes cleaned in (HDHL), crushed in (HCRC) and hydro-thermally prepared seed.
HUM Oil Pre-Presses (HPPR) is designed for pre-pressing in HUM Oil Seed Preparation (HPRP) for HUM Extraction (HEXT), or as the pre-stage for secondary pressing operation. The finish press processes cleaned in (HDHL) crushed in (HCRC) and hydro-thermally prepared seed.
With the modifications and the renovations made in the new model Oil Screw Presses, which are the latest product of HUM’s research and development activities,

❚ 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 made of special alloy, strengthened by means of heat treatment or customs manufactured with armor as an alternative; Worms 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 optimum 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.
SPARE PARTS FOR SCREW PRESS
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
HUM COOKING (HCOO)
Oil seeds must be cooked in cooker beforehand in order to improve oil productivity and to evaluate cake better. So, during pressing seed gains an appropriate structure and oil cell is easily broken down, releasing oil and humidity. 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.
HUM Cooking is engineered for the cooking and/or conditioning of oilseeds during the HUM Oil Seed Preparation (HPRP) process previous to the HUM Oil Pressing (HPRS) or HUM Flaking (HFLK). Vertical multi-stage cookers with floors or horizontal rotary conditioners of simple stage and big size are used. Besides sterilizing and decontaminate the seeds, this process objective is to provide them with plasticity, reduce the oil’s viscosity and clot the proteins.
❚ 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
❚ Because seed is blended by blades in the pan, it is also ground. Thus the broken membranes of cells gain a tender and brittle structure with the influence of heat.
❚ Water surrounding oil clusters is removed with the dehumidifying
❚ Because humidity level of seed drops to around 4-4,5%, the useful capacity of the press is increased
THE PROPERTIES THAT MAKE HUM COOKER EXCLUSIVE;
❚ PLANETARY REDUCER, the planet reducer providing silent operation, long life and high productivity
❚ BLENDING ARMS, the tips of arms having an angle of 35 degrees with cooker surface is designed to prevent accumulation of seeds; they are also designed not to leave oil seed at the bottom of the cooker and not to deform cooker sheets, combined in a manner to form a strong construction.
❚ DEHUMIDIFIER, a system with dehumidifier chimney, connected to each cell of the cooker by adjustable flaps, through stainless steel ventilation fan.
❚ PIN JOINT, cooker steam trays bottom and top sheets are joined by pins.
❚ PRESSURE TEST, pressure test made by specialists pursuant to the regulations about pressurized vessels and the CE certificate received from the accredited organizations of the world.
HUM OIL FOOTS SEPARATOR (HFSP)
Before sending the foot oil to the decanter or metallic filters for filtration, it’s needed to use HUM Oil Foots Separator (HFSP) for decreasing foot content in the oil to a reliable levels. Foots Separator is an equipment with a shape of prismatic tank, taking the foots from the deep by the help of chain pallets and separating these foots from the oil by the help of special section screens which are located on top of the oil level, and discharging these foots by the help of screw conveyor.
HUM CAKE COOLER (HCCL)
The temperature of oily cake coming from screw press, is too high for processing in the extraction. In order to enter the cake into the extractor, it’s temperature is needed to be decreased to 50 - 55 ’C. HUM Cake Coolers (HCCL), such as horizontal type, with pallet, with fixed special sectional screen, with aspiration system are used for cooling of many kind of oily seed cake.
