Batch plants
 Based around the central equipment, the batch
cooker, Batch Plants are conceived for the rendering of raw materials
providing the most flexible method of treating the full range and
capacities of all types of animal by-products.
As
well as the drying of products, the versatility of the batch cooker
allows sterilisation and hydrolisation operations to be performed when
the raw material process or regulations so require.
Following
the adequate preparation of the raw materials by means of size
reduction, pressing (feathers and pig hair), coagulation (blood), or
hydrolisation (feathers) the drying of the material in the batch cooker
is undertaken. The dried product is discharged from the cooker and then
undergoes a series of operations which separates the protein meal from
the fat and then further processes and refines each end product in a
series of operations (draining, pressing, cooling, milling, sieving,
storing, decanting etc) so that the highest quality and market value of
end product is obtained.
The addition of
solutions from TREMESA which treat cooking vapours and air arising from
processing guarantees the minimum environmental impact of such plants.
TREMESA,
S.A.U. facilitates the control of the overall process and equipment
(and therefore repeatability of end product qualities) by offering a
full range of control options up to fully integrated PLC control
depending on the requirements of the customer.
Continuous rendering processes in poultry slaughterhouses
 Large slaughterhouses and specialised collecting
Rendering companies need specialised rendering processes to obtain the
maximum end product quality with lower operational costs to maximise
the profitability of their operations. The use of continuous
hydrolisers for feather, disc dryers and continuous cookers for the
offals and carcasses together with equipment such as continuous blood
coagulators allow a complete range of possibilities to achieve the
highest qualities for large capacities in continuous operation.
- Coagulation of blood and posterior separation of coagules with up to 55% moisture content.
- Feather hydrolysis with unbeatable levels of digestibility (>85%).
- High energy efficiencies for the drying cycle via disc dryers, tubular dryers and continuous dryers.
- Optimum
pressing results obtained by adaptation of our presses to meet the
requirements for poultry material which is low in bone content.
- Minimal
environmental impact of plant operation due to the application of
Thermal Oxidation technologies (Recuperative or Regenerative) in the
treatment of processing vapours and critical extraction air from point
sources.
