Definitions

  • the invention relates to a cleaning device for cleaning components which are contaminated with fats and / or proteins and / or collagens and cartilage, bone or tooth residues.
  • Components are understood to mean all types of devices which, as a part or as a whole, can be subjected to the cleaning process. For reasons of use, these components are subject to the function that they come into contact with particles which, in particular under certain physical connections, adhere to the component such that a purely mechanical removal, for example with the high-pressure jet, is not possible. This also eliminates automatic cleaning in this conventional manner.
  • the particles that are stored on the components may have, for example, proportions of fat or proteins. However, these are not limited thereto. Rather, in the following under particles everything understood that which is suitable to deposit on components and can not be removed there with a high-pressure jet.
  • the component is contaminated with the particle in this case. particle are thus such materials containing protein and proteins, for example, may consist of cartilage, bone and tooth residues.
  • the cleaning devices known from the prior art have the disadvantage that the particles that adhere very strongly to the components of the device can not be sufficiently removed. Especially in holes and undercuts accumulate these said particles that only can still be removed mechanically with tools by hand. However, this is not sufficient for a reliable and proper cleaning. In addition, this costs additional time and is very much dependent on the subjective feeling of the person who cleans the product. Especially the deposited particles in the holes can not be removed by high-pressure jetting alone.
  • the method or device is not suitable because the fats and proteins and, in the case of perforated discs for meat grinders, the meat remains stuck in the holes.
  • the perforated discs would be disordered in the cleaning device described and would lie on top of each other, which in turn leads to a poor cleaning result.
  • the object of the invention is to provide a device and a method with which a preferably automatic and adequate cleaning of components that are exposed to fat and protein, is achieved.
  • the basic idea of the invention is to expose the contaminated components in a tempered fluid bath above the boiling point.
  • the temperature reaches a range above 100 degrees Celsius (when using water as a fluid), whereby systemically also the pressure increases and thus It has been found that by increasing the temperature above the boiling point and placing in a pressure-resistant container, the particles change their structures and can be removed more easily in a next step, for example by spraying. Without exposure of the particles in temperature ranges above the respective boiling point of the fluid surrounding the particles, little or no change in the structure of the particles takes place. Thus, the physical or chemical change of the particles due to this process, a slight detachment is achieved.
  • the boiling pressure is 1 bar. If the boiling temperature is increased to 180 degrees Celsius, then the boiling pressure of about 10 bar sets. In fact, it has been shown in experiments that at 180 degrees Celsius fluid temperature and thus a connected pressure of about 10 bar, a significantly better cleaning result can be achieved. This range between 150 and 190 degrees Celsius can be regarded as a work area. This creates a pressure in the range of 5 to 10 bar.
  • alkaline fluids such as potassium hydroxide or sodium hydroxide dissolved in water may be used. This further improves the cleaning performance.
  • An advantage of the underlying device is that several components can be processed simultaneously, so that a cleaning of many components is possible at the same time.
  • the cleaning process is designed such that it could run automatically.
  • the advantage of the device or the method is that protein and proteins, especially bone, cartilage and tooth residues that can not be removed at 60-80 degrees Celsius otherwise operated at low pressure and only at low pressure, now in a short time, preferably less than 1 h, can be completely removed.
  • the cleaning device 1 essentially consists of a pressure chamber 2 which can be charged with the material 3 to be cleaned.
  • the material 3 to be cleaned is arranged on a holding device 4.
  • the pressure chamber 2 is dimensioned such that the material to be cleaned 3 in the pressure chamber 2 can be completely accommodated.
  • the pressure chamber 2 has a cover element 4 and a receiving area 5 for the material 3 to be cleaned.
  • the cover element 4 encloses in the use state of the cleaning device 1 to be cleaned Good 3 and is in operative connection with the receiving area 5 such that the enclosed cavity 6, which is at least partially filled with the material to be cleaned 3, filled with a fluid or acted upon can, wherein the temperature of the fluid is above its boiling point.
  • an inlet 7 is provided in the region of the cover element 4, via which air or a fluid can be introduced into the cavity 6 selectively.
  • the fluid and / or the pressure can be discharged via a drain 8, wherein the drain 8 is arranged in the region of the lowest point of the cavity 6 with respect to the acting gravitational force.
  • heating elements 9 are provided in or adjacent to the cavity 6. This heating element 9 thus has the property to heat the introduced fluid so that in the pressure vessel, the temperature is preferably reached far above the boiling point of the fluid and thus can use the much faster and more effective cleaning effect.
  • Corresponding control and regulation technology 10 is likewise provided in the cleaning device 1. It serves to regulate the inflow and outflow of pressure and fluid, to measure physical properties in the pressure chamber 2 and to provide appropriate control variables.
  • the process associated with the cleaning device 1 or the process can proceed automatically, wherein the individual process steps are monitored or controlled by the control and regulation technology 10.
  • the loading of the cavity 6 of the pressure chamber 2 can be done in different ways. Either the material to be cleaned can be introduced into baskets or other receiving devices, so that a simple insertion and removal from the pressure chamber 2 is possible.
  • a holding device 13 is proposed.
  • This holding device 13 consists of a frame 11 which is comparable to a basket for a dishwasher. In it, the items of the goods 3 are listed, which are to be cleaned.
  • the holding device 13 has at least one spray arm 12. This wets or sprays the material to be cleaned 3 during the cleaning process in certain defined periods of time and is similar to the spray arm of a dishwasher. This means that no separate drive is available.
  • the rotation of the spray arm is effected exclusively by the fluid pressure which passes through the spray arm 12.
  • the holding device 13 has several levels E1 to En, wherein the number of levels is not limited. Each level E1 to En has a spray arm 12 which sprays the material 3 to be cleaned.
  • the invention is not limited to the dishwasher-type training.
  • Guts is provided externally drive the spray arms (for example, by an electric motor) or instead of the spray arms or in addition to the spray arms to use spray jets, which are aligned with the holes.
  • the holding device 13 has in the in the Fig. 1 illustrated embodiment wheels 14. This makes it possible to easily feed the pressure chamber 2, regardless of whether it is a table or floor unit of the cleaning device 1.
  • the cleaning process for the material to be cleaned 3 in the cleaning device 1 is divided into different steps.
  • the cleaning device 1 is preferably used to clean greasy and protein-rich material. This can be understood, for example, writing a meat grinder, through the openings meat has been pressed under high pressure. Due to the use of the discs, they are greasy and deposit on them as well as in the (component) bores protein-containing particles or bone, cartilage or tooth residues which are difficult to remove in an automatic process, at least within a reasonable period of time (in the Usually less than 2 h).
  • the material 3 to be cleaned is introduced into the holding device 13.
  • the pressure chamber is designed such that it has means that the Pressure chamber can be brought into an open position. In this open position, the material to be cleaned in the pressure chamber can be introduced and removed from this. The further position that has the pressure chamber is the closed position. This serves to clean the material to be cleaned. Since the pressure within the pressure chamber increases, means are provided which cover the pressure chamber functionally.
  • a coarse cleaning is carried out by means of a fluid radiator, for example a water jet, so that the easily removable particles are already removed from the material 3.
  • a fluid radiator for example a water jet
  • the lid member 4 of the pressure chamber 2 opens, so that the holding device 13 with the material to be cleaned 3 in the cavity 6, formed by the cover member 4 of the pressure chamber 2 can be introduced.
  • the cover element 4 closes so that the cavity 6 is in fluid communication with the environment only through the inlet 7 or drain 8.
  • the fluid flows into the cavity and the spray arms 12 rotate or move across the items to be cleaned and thus carry particles that lie on the material to be cleaned from. Subsequently, the fluid is drained.
  • the cavity 6 is flooded with a fluid so far that the material to be cleaned 3 is wetted.
  • the heating element 9 the temperature of the fluid beyond its boiling point is increased in water to at least 100 degrees Celsius).
  • the pressure within the pressure chamber 2 increases beyond the ambient pressure.
  • pressures of up to 5 bar can be achieved (depending on the degree of soiling on the material 3).
  • the fluid may have other than the neutral pH.
  • the fluid is either acidic or basic.
  • a further improvement of the cleaning performance can be achieved by using ultrasound.
  • Ultrasonic vibration elements that generate the ultrasound can be arranged on the wall of the cover element 4 or else in the receiving region 5.
  • the use of ultrasound can be done both at normal fluid temperature (for example, room temperature) or at elevated temperatures. Regardless, the ultrasonic cleaning can be done in the pressure vessel in which the material to be cleaned is already arranged. Alternatively, the ultrasonic cleaning process can also be connected downstream with another device.
  • the increase in pressure due to the increase in the temperature of the fluid above the boiling point of the fluid lead to a previously unknown cleaning effect.
  • the fat and protein parts and / or cartilage, bone or Tooth residues that adhere to the material to be cleaned can be removed without residue.
  • the proportions become powdery and can thus be removed simply by a subsequent rinsing process and / or ultrasound application.
  • the invention is not limited to the cleaning of perforated discs, in particular meat mincers. Rather, all objects can be cleaned with this device and the associated method, which are contaminated in particular by protein and / or fats.
  • the device is suitable for the cleaning of tools in the meat processing industry, as adhere to these Werk manufactureen the particles described above. But even in medicine, for example in the pathological or histological area, such cleaning devices are quite conceivable.
