  EPS Pasteurization Systems with Plate Heat Exchangers
This series of pasteurizers include our EPS90, the MOST POWERFUL pasteurizer
in the world with a capacity to process 20,000 kg/hr of whole egg and egg
whites products.
Our pasteurization systems are the safest and most efficient
in the market. All our systems include features that guarantee that every
particle of product will always be pasteurized and that no raw product will
enter the pasteurized product section of the system. Our special double-wall
regeneration section is designed to operate without the need for low
efficiency water-egg-water systems or pressure differential controls.
Our
holding tube design reduces the product loss during transitions and guarantee
the proper holding time at the right temperature always. Non-sloped holding
tubes used in pasteurization systems increase the amount of product that
mixes with water during transition and can reduce the holding time due to
air-pockets trapped within it.
For each system we offer options such as
homogenizers (shear or high pressure), PLC with touch screen interface,
pressure differential controls and single or dual divert valve assemblies.
All our systems include USDA/3A approved insulated/sloped holing tubes
available from 2.5 to 5.0 minutes, depending on the time-temperature
combination for the expected Log reduction.
EPST Pasteurization Systems with Tubular Heat Exchangers
These skid-mounted systems are designed to process specialty egg products
where pieces of non-soluble ingredients have been added like diced onions,
peppers, etc. for value added products. Our series of tubular pasteurizers
are available in a wide range of capacities from 500 to 10,000 liters per hour.
They can also process standard egg products, but the energy transfer is not
as efficient as pasteurizers with plate heat exchangers. We use a unique
heat exchanger with spiral corrugations that maximize turbulence inside the
heat exchanger for higher heat transfer efficiency. Depending on the
application, our pasteurizers use a combination of dual-tube, triple tube or
multi tube options.
For each system we offer options such as homogenizers (shear or high
pressure), PLC with touch screen interface, pressure differential controls
and single or dual divert valve assemblies. All our systems include USDA/3A
approved insulated and sloped holing tubes available from 2.5 to 5.0 minutes,
depending on the time-temperature combination for the expected Log
reduction.
Plate Heat Exchanger with Hydraulic Closer
On our large capacity plate heat exchangers we offer an option for a hydraulic
closer. This system relies on 2 or 4 hydraulic rams that open and close the
plate heat exchanger in less than 3 minutes. The use of hydraulic rams instead
of high wear screws rotated by hydraulic motors reduces both the time to
open and close the system and the maintenance costs. The hydraulic rams
feature adjustable locks that allow the heat exchanger to remain closed
without pressure in the lines.
Based on the type of products to be pasteurized we have two different
models: Pasteurizers for plain products and Pasteurizers for high viscosity
products (10-12% salted yolks, 50% sugar yolks, etc.) The main difference
is in the streaming of the plate heat exchanger and the amount and location
of positive displacement pumps.
Diamond Pasteurizers are designed to safely and efficiently
pasteurize egg products. Our high temperature Plate Heat Exchanger
designs allow for high temperature (65ºC-69ºC+) pasteurization for
extended periods of time to maximize shelf life and reduce processing costs.
All our pasteurization systems are pre-fabricated and skid mounted for a quick
and easy installation. All sanitary welding is done under controlled conditions
in our factory, with a minimum amount of work required to connect the
system to the product inlet and outlet and utility connections.
Compact Systems
Several Years ago we introduced the “Breaker in a Box Concept” and since
then we have further developed the concept of pre-fabricated processing
plants.
The “Compact System” consists in a completely integrated system to
process eggs into whole egg products. The system incorporates a breaking
machine, filtration system, pasteurizer and a semi-automatic packaging
system. It also includes a steam boiler, glycol chiller and air compressor.
Ready for operation within 24 hours after arrival at the customers building.
The systems can later be re-configured and turned into a standard egg
breaking plant for separated products. The filtration and packaging systems
can be detached and integrated into the future filtration and cooling system
and into the packaging room respectively.
Log Reduction
To determine the time and temperature at which each product should be
processed, we use the “Thermal Destruction Charts”, specific for each product
This type of chart shows the Log reduction at different time and temperature
combinations.
By changing the temperature we can achieve the same Log reduction with
different holding times and vice versa. It is important to know the bacterial
load of the product to be pasteurized to be able to select the treatment that
will guarantee product safety with the least amount of damage to the egg
product. This technology allows us to design the pasteurizer with the highes
Log reduction to achieve the longest shell life possible.
