Definitions
- the invention relates to a method for separating volatile substances from solid or liquid materials, in which the material for dispensing the volatile substances is contacted with a dry or moist gas stream, which is optionally circulated.
- US Pat. No. 4,251,923 discloses a process of the type mentioned at the outset, in which a combination of vacuum drying and drying with a dry gas stream or food or pharmaceutical dispersed or comminuted in water is used.
- the circulated gas stream for example nitrogen, is passed over an adsorption layer, which binds the water vapor content and at the same time retains aroma substances escaping from the material; these can then be released as a liquid and returned.
- the method is practically only suitable for solutions or dispersions of the material in a solvent.
- Materials with sensitive cell structures cannot be treated with this method without a loss of quality, since they cannot be converted into a dispersion and cannot be placed under vacuum without the cell structure being severely damaged.
- the object of the invention is now to provide a method for separating volatile substances from solid or liquid, in particular animal and vegetable materials of the type mentioned at the outset, which permits simple and inexpensive treatment of sensitive material without loss of quality.
- the method of the type mentioned at the outset is characterized in that the gas stream consists of an oxygen-poor or essentially oxygen-free gas or gas mixture which can contain water vapor up to the saturation value, is contacted with the material and the volatile substances are absorbed in the gas flow takes place at a pressure which is given by the working pressure of the gas, which is in the range> 1 bar to 30 bar, preferably up to 16 bar.
- the method is to contact the volatile material with an adequately low-oxygen gas stream, which absorbs the volatiles to subsequently pass them through Decrease in pressure or temperature, or by adsorption or chemical reaction.
- the desired process temperature is obtained by heating the gas or by radiant or convective heat.
- the gas pressure in the mostly closed system is regulated by the pressure of the supplied gas or gas mixture. No evacuation.
- process gas used and its mixture depends on the sensitivity of the substances to be treated. Gases are generally used which prevent or reduce chemical, enzymatic or other undesirable reactions in the material during the treatment. Such gases are in particular carbon dioxide, carbon monoxide, sulfur dioxide or nitrous oxide or mixtures thereof.
- part of the gas can also consist of air or nitrogen.
- the proportion of air and / or nitrogen is not more than 80%, preferably not more than 50% and particularly preferably about 20%.
- the gas or gas mixture can be dry or contain water vapor up to the saturation value.
- Carbon dioxide is preferably used. However, it can be beneficial to use carbon monoxide. Add sulfur dioxide or nitrous oxide if a reducing or more bactericidal atmosphere is desired. In the case of sulfur dioxide, this addition is max. 50% (v / v), preferably not more than 20%, in particular up to about 5%. In the case of a large number of sensitive materials and substances to be separated, it has surprisingly been found that the process described brings considerable quality advantages over conventional separation methods.
- the processing temperature which is normally higher than 0 oC, can be relatively high for less sensitive substances and can even reach 120 ° C. Prefers are ranges from 30 to 80 oC, but for most sensitive sausages the temperature should be between 30 and 50 oC. Depending on the field of application of the process, a compromise must be chosen between protecting the material and the speed of the separation process. It may be advisable to initially keep the process temperature lower so that substances with higher volatility can be separated first. Afterwards, the less volatile substances are also separated at a higher temperature.
- the process pressure will preferably be selected in the upper range, since at higher pressures the gas flow per volume has a larger mass of all components, including the water vapor component, and thus heat and mass transport are increased. Due to the higher costs for pressure-resistant devices, working at medium pressures is recommended. Preferred process pressures are 2 to 10 bar, in particular 2 to 6 bar.
- the material to be treated is flowed through in the manner indicated for a period of time which is sufficient for the extensive removal of the volatile substances.
- This treatment preferably extends over 1 to 48 hours, in particular over 4 to 24 hours.
- the gas stream should be circulated and the volatile substances contained therein separated at a suitable point in the cycle. Cooling and / or relaxing are suitable for this, the latter especially when working at higher pressures, since the gas cools down at a simple nozzle and from the condensed volatile substance can be separated. Subsequent compression will warm it up again.
- adsorbers and scrubbers are also suitable for taking up the volatile substances from the gas cycle.
- the method relates to the extraction of valuable ingredients or the removal of undesired accompanying substances from organic or inorganic chemicals, raw and auxiliary materials and building materials.
- organic or inorganic chemicals raw and auxiliary materials and building materials.
- water can be separated from a wide variety of materials.
- accompanying substances made of plastic materials can also be separated, e.g. Acetaldehyde from terylene granules.
- the method relates to the extraction of valuable ingredients or the removal of undesired accompanying substances from animal or vegetable material.
- materials can in particular be fruit, vegetables, mushrooms, berries, bulbs, cereals, nuts, grapes, herbs and other plants and their fruits, or also meat and other cell material from warm-blooded animals, fish, shellfish and molluscs, microorganisms and others Cell material.
- Aromas or aroma fractions as well as flavorings are particularly worth mentioning as extractable valuable ingredients.
- Accompanying material that can be separated from the insert materials mentioned is, in particular, water.
- the method according to the invention is used in particular to preserve vegetable or animal materials which, as such or rehydrated, are preferably used for the preparation of foods or pharmaceuticals.
- the device has a conditioning container 1, in which perforated plates 2 are arranged one behind the other in the direction of flow of the gas stream.
- the dry protective gas flows in on the underside of the conditioning container 1 and leaves this water vapor-laden on its upper side;
- the perforated plates 2 are each horizontally transverse to the flow direction of the protective gas and follow one another vertically in the flow direction.
- the material to be dried as indicated schematically in the drawing, so that the protective gas stream passing through the holes in the perforated plates 2 sweeps over them.
- the protective gas stream comes dry via a circuit line 3 and is brought to the desired conditioning temperature by a heater 10 before entering the conditioning container 1. After entering the conditioning tank 1 through an inlet 4, it leads water vapor away from the surface of the material and, loaded with the water vapor, leaves the conditioning tank 1 through an outlet 5. Via the circuit line 3, the steam-laden protective gas stream reaches a water separator 6 by he can relax via a nozzle 8. Due to the cooling that occurs, the water condenses on the inner surfaces of the water separator 6; a Wasserablabilityhah ⁇ 7 serves ,, to drain the water separator 6 at suitable times.
- the loaded gas mixture is removed from the upper gas space, expanded to normal pressure, cooled with ice water and separated from the aqueous condensate.
- the gas mixture is compressed to 6 bar in a compressor, warmed to process temperature and returned to the dearomatization process.
- the aroma condensate is worked up, the pulp freed from volatile aroma substances is then concentrated and spray-dried after the addition of soluble starch. 2.
- a gas-tight horizontal tube 1.3 m in diameter and 4.0 m in length there is an endless sieve which has a contact surface of 3 m in length and 1 m in width. This sieve moves at a speed of 1 m / min. It becomes coarse in the purest possible atmosphere of 80 oC hot carbon dioxide
- Ground Arabica part of a roasted coffee mixture intended for extract is evenly placed on the beginning of the sieve belt and, during further transport, both turned over several times by baffles and heated to 80 to 100 oC under a chain of heat radiators. After the outlet, the coffee is quickly cooled and placed in the storage silos of the extract plant.
- a batch of 1000 kg of terylene granules is placed in the container above the sieve, which is associated with acetaldehyde due to the production process. After venting and filling with carbon dioxide and heating the gas to 70 oC and 12 bar with circulation, so much hot water is injected into the circulating gas that the water vapor saturation pressure is almost reached.
- the gas circulation rate is now 20 m 3 / min.
- 200 1 / min of hot moist gas are removed from the system and cooled to values close to 0 ° C in a cooling system without pressure change, with what The acetaldehyde is also separated.
- the cleaned gas is returned, and at the same time a quantity of fresh water corresponding to the separated condensate in order to keep the circulating gas constantly moist.
- the process described is first ended by switching off the water supply and then drying the system by simply circulating the gas over an hour. Now the gas is released and the: cleaned granulate is removed.
- a standing, cylindrical conditioning container with a diameter of 1 m and a height of 1.5 m, which has a central gas inlet in its bottom, there is a perforated plate insert with 5 perforated plates arranged one above the other for receiving lumpy goods.
- the container After filling with material to be dried, the container is closed pressure-tight by a lid and is first flushed with gas and then pressurized.
- a gas line leads from the cover to a nozzle, which opens into a flash tank, which allows the mixture cooled by the flash to be separated into condensate, which is drained off, and gas. From there, the gas line leads to a compressor, in which it is brought to the conditioning temperature.
- the dry gas now gets back into the circuit via the bottom inlet of the conditioning container, it flows through the material and absorbs its moisture.
- 150 kg of finely chopped boiled pork can be cooked at 70 ° C within 6 hours at a pressure of 8 bar and a compressor suction rate of 500 1 / min. be dried in a 1: 1 mixture of carbon dioxide and nitrogen.
