Detailed description of the invention
The inventors of the present invention have shown that it is possible to preserve the quality of solids (for example, fish wastes) by reducing the process pressure in a drying mill. It is an advantage to easily degasify the feed by creating vacuum environment. At the same time the drying process can get benefit from centrifugal forces.
Thus, the present invention provides a process and an apparatus which are capable of drying a mixture containing solids, liquids and gasses in any ratio. Examples of such compounds can be rubber, composites, offal, bio wastes, organic products and organics by products.
The concept is to establish an efficient condition in the reaction chamber so that low temperature evaporating takes place, in order to dry the solids in the above mentioned mixture.
The process may be enhanced by additives such as catalysts,Chemicals, solids and liquids prior to or during the process.
The process occurs in one or more chamber(s) which may be in parallel or series. The mixture (hereinafter referred to as the "feed" or "feed material" or "feed mixture") enters into the chamber(s) by a feed pump enhanced by sucking created by vacuum. Then a portion of liquids is separated by centrifugal forces and discharged from the chamber. The next step is degasifying the feed by the vacuum. The degasified gas is mainly air which may affect negatively on the dried solids at higher temperatures. The feed is heated then to a desired temperature. It may be preheated as well.
As mentioned, the process occurs under a vacuum condition. The required vacuum pressure depends on the desired result. For example the pressure can be between 0.05 barg and 0.99 barg.
The preheating temperature, the heating rate, the process temperature and any other parameters depend on the desired result and can be determined by a skilled person.
The chamber(s) has/have at least a rotor and/or a shaft (impact means) that may, for example have discs, propellers, arms, blades with any connection in between; fixed,
hinged, removable or adjustable. A portion of the liquid in the feed is extracted by the centrifugal force created by the rotor.
The vacuum is degassing the feed that makes the final dried solids quality higher. Then the feed mixture is heated by friction generated by the rotor/shaft. The rotation may make a fluidized bed with large surface for efficient transfer of the thermal energy. Heating may be supplied from other sources in order to maintain the process temperature or any other reason. For example the rotor/shaft or the chamber may be heated by other sources and/or the feed can be preheated.
The friction between the feed mixture in the fluidized bed and the impact means may be enhanced by adding solids such as sand, glass or metal pieces to the feed prior to or inside the chamber(s). The solids may remain in the chamber(s) or may exit the chamber. The retention time depends on process conditions, composition of the solids and desired result.
The apparatus has one or more inlet(s) and outlet(s) to feed in feed mixture and transport out all the phases (solids, liquids and gasses/vapour).
This process/apparatus may be used independently, in connection with, or as an integrated part of another process(es)/apparatus(es) onshore or offshore.
A preferred embodiment of the reactor according to the invention is shown in figure 1.
Figure 1 is a schematic drawing of a reactor 10 with a reaction chamber 12 with inlets 22 for feeding a feed material, and an outlet 24 for evaporated material and an outlet
26 for dried or cleansed material. The reaction chamber also contains an liquid outlet 27 for removal of liquid extracted from the mixture. The reactor 10 contains a rotor 14 within the reaction chamber 12, and the rotor is equipped with a plural of impact means 16. These impact means 16 can be discs, propellers, arms and blades, and can be, with regard to the rotating rotor, fixed, hinged, removable or adjustable.
Rotation of the rotor 14 will effect contact between the feed material and the impact means, and the rotation and the friction established will create a fluidized bed 18. The temperature in the fluidized bed 18 will increase and evaporable liquids will evaporate.
The reaction chamber 12 of the reactor according to the invention has one or more means 25 for regulating the pressure of the reaction chamber 12. The reactor 10 is thus capable of conducting a process according to the invention, i.e. a process where the reaction (separation or removal of oil or liquids) takes place at a reduced temperature at reduced pressure. The term "reduced temperature" means that the temperature of the process can be lower than the normal temperature at atmospheric pressure.
Experimental section
The aim of this study was to find out whether the reaction temperature could be decreased sufficiently during drying of a fish waste product to produce a dried fish meal. The prior art teaches that the process temperature should be 10-20 degrees centigrade higher than the boiling temperature of the liquid to evaporate from the waste in order to dry the solids efficiently.
Several test samples were dried in a friction dryer. A friction dryer converts kinetic energy to thermal energy by creating friction in the waste. A drive unit sets a series of shaft mounted hammer arms (impact means) in motion inside a cylinder shaped process chamber (also referred to as the hammer mill or just the mill). The waste material was forced towards the inner wall of the process chamber where the kinetic energy from the rotating arms will be transformed to heat by friction. Liquids in the waste material evaporate and leave the chamber, and new waste is pumped in. Solids are discharged through an output. The hottest spot in the process is the waste itself, and the liquid is under influence of the process temperature for maximum a few seconds. A representative example of such a friction dryer is the TCC<®>from Thermtech, Norway.
The test samples used in this example are various waste products from the fish farming industry, i.e. fish waste products. The main object of the experiments is to provide an efficient drying, i.e. removal of water as the liquid component.
Drying of fish waste materials represents a considerable problem relating to the "gluey" characteristics of the material. During drying, i.e. removal of water, and also for removal of fish oil, within certain ranges of dry material to moisture a glue zone is established, and the particles of the waste material will dump together, making problems for the drying equipment and reduces product quality and drying efficiency. It is known from the prior art that the glue phase can be avoided by introducing only small amounts of waste material into the friction dryer, so that the waste material is rapidly dried in contact with the fluidized bed of the heated material.
The results obtained by the present invention show that the glue phase also can be avoided by using a process temperature that is actually lower than the boiling temperature of liquid that shall be evaporated (i.e. water in the context of drying a waste material).
The results show that the reaction temperature can be reduced by about 10-20% of the boiling temperature, and by about 20-30 % of the temperature used in prior art friction dryers when the pressure is lowered to -0.5 to -0.6 barg.
In the context of the present invention, the term "barg" is defined as a unit of gauge pressure, i.e. pressure in bars above ambient or atmospheric pressure.
Since many biological substances are sensitive to high temperatures, this lowering of the reaction temperature will also provide a better, and less decomposed end product.
Example 1 - Evaporation of water from fish waste products
Various fish waste materials were dried;
- White fish fillet cuttings
- White fish entrails (without liver)
- Defatted salmon entrails
The waste material is ground in a mill with a mesh diameter of 8 mm, and is pumped to the reaction chamber of a friction dryer. The rotor with the hammer arms (impact means) is rotated and a bed of waste material is formed on the inner wall of the reaction chamber. The temperature of the bed increases due to the transfer of kinetic energy to thermal energy in the waste bed, and water in the added waste material will rapidly evaporate in contact with the heated waste bed.
The various fish waste test samples were tested at different temperatures in the reaction chamber, and at different pressures, especially at normal atmospheric pressure and at various levels of reduced pressure (vacuum) as indicated in the
tables below.
The results given in the table below show that the temperature for evaporation of water from the moist fish waste material can be reduced from 110-120 °C (as known from the prior art) to temperatures below 95 °C, more preferable 90 °C, and more preferable 85 °C when the pressure is reduced to a range of -0.4 to -0.5 barg.
