Definitions
- the present technology is related to the aquaculture industry and food production in general.
- the present technology is related to a system for the processing of food portions, which achieves an optimization of the thermal potential energy, even under discontinuities in the loading process of the food portions to a cooling tank, due to the exchange between the incoming object and the medium, with a smaller volume of cooling.
- the device and method are designed to cushion unproductivities and ensure a more efficient average productivity of the process.
- spiral tanks spiral tank or bleeding tank or chilling tank
- tank with endless screw or Archimedean screw are used to cool biomass or food product or fish, specifically, in storage ponds.
- spiral fish are inserted to be bled after being slaughtered to be bled or after evisceration.
- the fish bleeding process must be done between 18°C and -1°C, but the fish to be bled are at a temperature that corresponds, normally to their environment, which in the case of the sea is between 2°C at 18°C, which generates an increase in the thermal load of the fluid that is inside the spiral tank(s).
- the post-evisceration cooling process is carried out between 18°C and -4°C, which depends on the evisceration temperature.
- liquid ice in English: Fluid Ice or slurry ice
- ice + water in English: fresh or salt water
- RSW systems for its acronym in English, is also used.
- Refrigerated Sea Water which refrigerate salt water without changing state, always keeping it in a liquid state.
- cooling fish In the case of cooling fish, it is a widely used system since it eliminates the risk of freezing, since the fish freeze under 2 due to their biochemical composition (presence of lipids) and the RSW cooling system works at -2° C (normally a few degrees Celsius more). In this way, there is no risk of freezing compared to other methods (flake ice, Fluid Ice, etc.) used in the state of the art.
- the spiral tank fulfills the function of cooling the biomass, normally they are FIFO, (first in first out) in the process of side loading or front loading, the biomass or food product or fish to process are at a temperature higher than that of the fluid, which generates variations in thermal load according to the residence time of the biomass in the spiral tank, as the temperature of said biomass decreases, and since these must be for a minimum time inside the tank, it is relevant that the volumes of the chambers that receive the biomass are larger with respect to the volumes that have a lower external thermal load as a result of the biomass entered.
- a s the surface area of the body (m 2 )
- the total heat transferred (Qtotai) over time is:
- T ⁇ initial temperature of the body in (K)
- the spiral tank fulfills the function of providing a residence time in order to provide a thermal exchange to the biomass.
- the operation is normally by FIFO system and the advance is by means of the progressive thrust of the helicoid generated by the rotation of said helicoid.
- the productivity of this type of equipment is given by the multiplication of the previous and subsequent processes, for example, if the productivity of the previous process is 80% and that of the subsequent process is 85%, it would deliver a total yield of 68 % (assuming inefficiencies do not overlap).
- a solution to the above is lateral loading, that is, if the product is counted (or weighed), it is feasible to load the Spiral Tank maintaining the same density for each compartment (units/volume or mass/volume).
- the cooling density (potential energy of temperature)/volume of the medium is a very relevant factor for sizing the spiral tank, since, at high thermal densities, the transfer becomes inefficient.
- aeration or air surge systems are used to agitate the medium, generating separation and improving the transfer by turbulent flow. It is also recommended to generate a recirculation to homogenize the temperature of the medium (since this temperature is higher in the area with the highest product density, also affecting the shortest residence time in the biomass tank.
- the volumetric density is the same, however, its temperature decreases, that is, the thermal potential energy is less and less, so the spiral tank becomes progressively more inefficient in the sections that have products at less temperature.
- the technology consists of a spiral tank with variable pitch, that is, as the Biomass advances and its temperature decreases, the density (Biomass/average volume) increases, in this way it seeks to maintain an adequate thermal potential energy/volume to optimize the process, along the spiral tank, maintaining a constant thermal load in each chamber.
- patent US3368363 discloses a process for freezing food using liquid refrigerant, which comprises a spiral screw with a fixed or variable pitch designed to quickly freeze food.
- the purpose of the appliance is to freeze food avoiding agglomeration and allowing the glazing on the outer layer, that is why in the first sections the products have a greater volume available, and once they are frozen, the volume of the sections.
- patent US3368363 does not achieve an optimization of the thermal potential energy with respect to the volume of a cooling fluid and does not achieve a shorter residence time of said biomass.
- patent US3368363 does not resolve the variability (discontinuity, dispersion or arrests) in the entry or exit of the biomass, that is, the load density of the chambers is variable according to the variability of the process before or after.
- each lock without the need for a greater volume of fluid in each lock or a longer residence time, where each lock is formed between the inner side of the tank and the blades of the helical screw, in the zone input of the biomass or food product or fish to be processed and less volume of fluid in the exit zone of the biomass or food product or fish to be processed.
- an adequate time is achieved inside the spiral tank, managing to obtain the desired temperature, which is between -2°C to 10°C, achieving an optimization of the thermal potential energy with respect to the volume of fluid, reflected in a lower biomass residence time and with a lower volume of cooling fluid.
- a helical, worm or Archimedean screw with variable pitch which compensates for the variability of the entry or exit of the biomass or food product or fish to be processed, through a greater volume of fluid, formed between the inner side of the tank and the blades of the helical screw, in the entry area of the biomass or food product or fish to be processed and a smaller volume of fluid in the exit area of said biomass, achieving an optimization of the potential energy thermal with respect to the volume of fluid, reflected in a shorter residence time of the biomass and with a lower volume of cooling fluid.
