Definitions
- the invention relates to a device for pressing, in particular in the sense of a screw press.
- the invention relates to a method for pressing.
- Methods and devices of this type are used to squeeze liquids out of a press cake, for example oil from oil-bearing seeds.
- a press cake for example oil from oil-bearing seeds.
- the material to be pressed is fed to a pressing device, for example designed as a screw press, in which liquid is removed from the press cake by mechanical pressing, so that solid and liquid components of the material to be pressed are separated from one another.
- Screw presses have a screw shaft that is rotatably mounted in a press chamber.
- the pressing chamber is delimited by a so-called sieve basket in a tubular shape, with the material to be pressed being fed in at a first end and the press cake being ejected at the second end.
- the sieve basket has peripheral openings, which are generally designed as slots running parallel to the axis of rotation of the screw shaft and through which the pressed liquid can escape from the press chamber. These slits are usually formed by the spaces between strainer rods arranged next to one another.
- the press cake After pressing, the press cake is used, for example, as animal feed or as a food supplement, so that certain quality requirements are met.
- PDI value protein dispersibility index
- AITC content allyl isothiocyanate content
- the AITC content also decreases with increasing temperatures during the pressing process.
- DE 10 2007 014 775 A1 proposes methods and devices of the aforementioned type that enable an improvement in the product quality of the oil obtained, in particular for use in the production of edible oil, which is achieved in particular by limiting the temperature of the extract to a maximum of 60° C. throughout extraction process is achieved through the use of supercritical CO2 as the extractant.
- this object is achieved by a device for pressing according to claim 1 .
- a further object of the invention is to specify a method for pressing with which the material to be pressed and/or the pressed liquid can be cooled during pressing without the disadvantages occurring when using supercritical CO 2 .
- this object is achieved by a method for pressing according to patent claim 14 .
- a pressing device is designed as a mechanical pressing device, in particular as a screw press, and has means for supplying a coolant into the pressing chamber.
- the coolant is directed onto the strainer basket exclusively or additionally from the outside, at least in certain areas.
- air or nitrogen is used as the coolant, with the respective coolant being able to be fed in liquid form into the compression chamber of the device for compression in preferred embodiments of the invention.
- nitrogen is used as a coolant compared to air, since this, in addition to the cooling effect, also contributes to a better product quality of press cake and pressed liquid, since oxidation of the products during pressing is avoided, and the risk of fire due to the displacement of oxygen is eliminated of the bale chamber is reduced.
- Flap seals are seals for flaps that form part of a housing or casing of a pressing device. These flaps serve to provide accessibility to the strainer basket of a device for pressing, for example for maintenance purposes, and at the same time shield the interior of the device for pressing from the environment. A sealing of the flaps supports this shielding, so that the escape of gases from the device for pressing into the surrounding work area is avoided.
- the flap seals are designed as rubber lips which are arranged on the edges of the flaps.
- flap seals are combined with aspiration of the press interior.
- sensors are installed on the side doors and cake flap to prevent the doors or flaps from opening during operation of the device for pressing or during the supply of coolant.
- the sensors are in the form of proximity switches or inductive switches, with which it is possible to detect whether the doors and/or flaps are closed.
- the sensors are integrated into a process control with which the supply of the coolant and/or the operation of the press can be stopped when a door and/or flap is opened.
- the temperature of the respective coolant is lower compared to the gaseous state at ambient pressure, so that the cooling effect on the press cake and/or the pressed liquid is higher.
- the means for supplying a coolant include at least one coolant source and at least one coolant outlet, which is arranged on the pressing device in such a way that the coolant can be introduced into the pressing chamber.
- the coolant source can be designed, for example, as a coolant container or reservoir in which coolant is stored under ambient pressure or possibly at a higher pressure, or as a device for generating the coolant.
- the pressing device particularly preferably has a plurality of coolant outlets.
- the at least one coolant source and the at least one coolant outlet are connected to one another via at least one coolant line.
- At least one coolant valve is preferably provided, via which the supply of coolant into the pressing chamber of the pressing device can be controlled.
- the at least one coolant outlet is arranged close to the worm shaft or in the worm shaft itself, so that the coolant is injected close to the worm shaft. This maximizes the path that the coolant has to take through the press cake before leaving the press chamber, so that the effect of the heat exchange between the coolant and the press cake is maximized.
- the injection must not be too close to the worm shaft, as the shaft could otherwise be damaged due to the low temperatures.
- At least one coolant outlet is arranged on the worm shaft.
- the coolant is injected from inside the worm shaft through a coolant outlet.
- the coolant is injected through coolant outlets projecting into the press chamber from the outside. This arrangement of the coolant outlets allows for easier retrofitting of conventional devices for pressing compared to injection from the screw shaft.
- the injection of the coolant from nozzles that are not arranged in the worm shaft has the advantage that the material of the worm shaft is not adversely affected by direct contact with the coolant at the feed temperature.
- the worm shaft can become brittle if the temperatures are too low.
- Temperatures of less than or equal to 5°C are critical for the material of the worm shaft, temperatures of less than or equal to 0°C are particularly critical.
- At least one temperature sensor is arranged in the screw shaft in the area where the coolant is introduced into the press chamber. With this, the local temperature of the worm shaft can be measured.
- At least one measured temperature value of the temperature sensor arranged in the worm shaft is used to control the feed quantity and/or the feed temperature of the coolant in such a way that the temperature of the worm shaft is kept above a temperature limit value in order to prevent damage to the worm shaft due to thermal stresses avoid.
- the injection of the coolant from the inside of the worm shaft through a coolant outlet and the injection of the coolant through coolant outlets projecting into the press chamber from the outside are combined with one another.
- coolant outlets protruding from the outside into the press chamber in embodiments of the invention these are arranged in areas in the conveying direction of the press behind throttle rings.
- this has a sealed area of the strainer basket in the area of the coolant outlets and/or in an area directly behind it in the conveying direction, in which area the coolant cannot escape.
- the coolant is conveyed longer together with the press cake in the conveying direction of the press, so that better cooling of the press cake is achieved. This reduces the escape of trub, i.e. press cake as a solid content in the pressed liquid.
- the means for introducing the coolant are arranged entirely or partially in a cooling ring which forms part of the press chamber.
- the length of the strainer rods in the installation area is adjusted accordingly in embodiments according to the invention.
- the amount of coolant supplied also plays a role in relation to the achievement of the effects according to the invention, in particular in relation to the throughput of the press cake.
- the pressing device has a measuring device for measuring the exit temperature of the press cake from the pressing device. With the aid of a corresponding dosing device, the amount of coolant supplied can be adjusted to set a target temperature for the press cake emerging from the press.
- a pressing method according to the invention comprises at least the following method steps:
- a material to be pressed or a press cake is introduced through a feed opening into a screw press and transported through a press chamber with the aid of a screw shaft and pressed in the process, so that a liquid is pressed out of the press cake.
- the pressed liquid exits the press chamber through openings.
- the coolant is preferably supplied to the screw press in the liquid state, as this is colder and the cooling effect is greater.
- the coolant is preferably injected into the press chamber in the area of the worm shaft, so that the cooling effect is improved and, if necessary, entrainment effects are achieved with regard to the pressed liquid.
- nitrogen is used as the coolant, particularly preferably liquid nitrogen.
- the method for pressing according to the invention is designed to implement part or all of the functions of a device for pressing according to the invention.
- the coolant is supplied in such a way that the screw shaft is locally cooled to a maximum temperature greater than 0°C, in particularly preferred embodiments to a maximum temperature greater than 5°C.
- a device for pressing according to the invention is used.
- a device according to the invention for pressing in embodiments is also designed to implement the method according to the invention in all disclosed variants.
- the following operating parameters are used in embodiments of the invention:
- the inlet pressure of the coolant is atmospheric pressure in embodiments of the invention. In other embodiments, a pressure below 100 bar is provided. In different embodiments of the invention, the coolant is injected under high pressure. In any case, the inlet pressure of the coolant is so high that it can be pumped into the strainer basket in corresponding embodiments of the invention.
- 100-1000 t/d seed equivalent for pre-pressing, 90-170 t/d seed equivalent for post-pressing and 30-100 t/d seed equivalent for finishing presses can be set as the mass flow for the press cake. In other embodiments, however, lower mass flows can also be covered.
- the ratio of the supplied mass fraction of the coolant to the total mass flow of the press is between approximately 0 and 25%. Excessive coolant input consumes an unnecessarily large amount of coolant and cools the press cake to an unnecessarily large extent.
- the press cake or the pressed liquid is preferably only cooled to such an extent that the process specifications with regard to the specified product quality are just achieved.
- the essential advantage in the product quality of the press cake that can be achieved according to the invention is the higher PDI value, which indicates the percentage of water solubility based on the total amount of protein in the product.
- the allyl thiocyanate content is crucial for the product quality.
- a value of 0.3 meq is aimed for for high-quality products, with a value of up to 0.26 meq being considered acceptable.
- the content of allyl thiocyanate decreases with higher temperatures, so that the target value of 0.3 meq can be expected in the range of an oil temperature in the range of about 70 °C.
- the usual oil temperature of conventional squeezing is approximately 100° C., so that a temperature reduction according to the invention is accompanied by a significant improvement in the oil quality.
- Another advantage of the invention is the use of inexpensive coolants.
- Liquid carbon dioxide is typically slightly more expensive than liquid nitrogen. Obtaining nitrogen from the ambient air yourself is even more economical when there is a high demand. Savings of 40 to 75% can be achieved depending on the cost of purchasing and delivery in an area. It is therefore a case-by-case decision as to whether delivery of liquid nitrogen or on-site generation, which requires a higher initial investment, makes more financial sense. This also applies to air as a coolant.
- a multi-stage pressing is realized by the serial arrangement of at least two cooled pressing stages. As a result, lower residual fat contents in the press cake can be achieved compared to single-stage presses / pressing processes.
