SureView Instruments manufactures Pulsed Electric Field Equipment in India for processing of food such as Milk, Vegan Milk, Oranges, Strawberries, Fruit Juices, Potatoes, Carrots, Meat, Wine, Yogurt, Coffee, Beans, Beet, Apple, Tomatoes, Sugarcane, French Fries, Olive Oil & so on.
Pulsed Electric Field (PEF) technology is a better substitute to heat treatment or preservatives for increasing shelf life of food. It kills microorganisms present inside foods such as Watermelon juices & thus increases the shelf life. Pulsed Electric Field increases the yield of your production such as up to 18% in Extra Virgin Olive Oil production. Also the colour, flavour, texture & nutritional value of any food is maintained.
Our company is part of the SCR ELEKTRONIKS group founded in 1975. Since 1975, we have built Electrical Equipment for Voltas, Teknic, L&T, Eaton, Philips, Siemens, Honeywell, Raychem, C&S, Wipro, GE, Salzer, Bajaj, Intertek, ABB, Legrand, Havells, HPL, Panasonic, UL, ERDA, ERTL, PSEG Nuclear, Blue Star, Al Fanar, Awal Gulf, Polycab, Carrier, V-Guard, Green Lumar, Thorn, AO Smith, Finolex, Indoasian, Whirlpool, Syska, Godrej, Crompton, Hager, CPRI and Nikdim.
For demonstration of PEF, please visit our Mumbai factory. We have made various treatment chambers as per your applications
The SureView Pulsed Electric Field Equipment consists of:
Signal Generator –
This is used for creating link voltage to the switching circuit. This is fully programmable through the Programmable Automation Controller. This means that any voltage determined by the control unit will be realised by this unit. This has over-current, short-circuit and other protections such as Input-surge protection and an electronic current limit. The Pulse height, duration & interval is controlled by this circuit.
Solid-State Switching Unit –
The solid state switching unit is used for actually producing pulsed-output and wave-shape. It gets the link-voltage as an input. This is a specially built part for the specific model of the Pulsed Electric Field Generator. This accomplishes flaw-less operation even at elevated temperatures.
High Voltage Pulse Transformer –
Depending upon the model of the PEF generator, a custom-made high voltage pulse transformer is incorporated to produce the High Voltage pulses so as to get pulsed electric field across the electrodes. Selection/Design of this will be determined by the HT level and duration of the pulses. The model in the photograph on this page is a 40kV PEF Generator with maximum 500µsec pulse duration. We make various PEF Generators from 5kV up to 150kV.
On all models, there is an additional protection on the transformer unit using mechanical interlock to prevent accidents while handling.
Programmable Automation Controller –
This is the control system and HMI of the Pulsed Electric Field Generator. All the components of PAC are industrial grade and are carefully selected to work in high voltage environment. The user can set –
• Peak value of voltage
• Pulse-width
• Number of pulses and interval in-between the pulses
• Mode – Single, Discreet, Burst or Infinite
As an option, the PAC can be interfaced using Ethernet or WiFi with Windows PC, Windows Embedded, or any PLC. We have taken in consideration all ‘accidental’ settings so you can use the Pulsed Electric Field Generator in your Automation project without any safety concern.
PC Based Operation –
We provide support to your software developers if you want to integrate our PEF Generator in your project. We also have a software team in our Mumbai, India factory who are expert in industrial automation and can build the software for you. We use NI LabVIEW to develop software to work with our Pulsed Electric Field Machines.
Treatment Chamber –
We offer treatment chambers that are custom-made for your application. The details of the same will be available with quotation on email. If you have a production-line or wish to use a chamber you have built for your specific application, the Pulsed Electric Field Generator has perfect provision to work with the same.
Oscilloscope –
The PEF Generator has isolated BNC connection for connecting your oscilloscope should you wish to see the pulses. We recommend using Keysight or Fluke oscilloscopes and they are available with our machine from us as an option.
Production Grade 40kV / 400Hz Pulsed Electric Field Equipment
Pulsed Electric Field Machine for Belt System
SurePEF Liqvius - 1 Stage Pulsed Electric Field Systems for Liquid Foods
This is a 1-stage treatment system for liquid foods. With this plant the juice is treated to inhibit the micro-organisms in the juice. This way the juice can be preserved by ‘minimal-treatment’ so that its color, flavor, nutrition value and taste is maintained (unlike thermal or chemical process).
The PEF treatment chambers are constructed in such a way that, maximum energy efficiency can be derived. The energy is directly inputed from your supply. This is converted in to high voltage pulsating electric field. The pulse-height, pulse-width, pulse-interval and duration are settable on the HMI.
Juice is fed to the SurePEF Liqvius plant for disinfection treatment through VFD controlled pump. There is a special arrangement in the liquid treatment chamber which provides the necessary treatment environment (turbulence etc.). This is designed such that all the liquid is uniformly and completely treated without increasing temperature of the juice so that the quality of the food is perfectly maintained. After the treatment, there is an arrangement to offer the juice for packaging or bottling.
Adequate care has been taken to insulate high voltages from ground voltage equipment. All the operation is automatic, no frequent adjustments are required.
SurePEF Liqvius Max - 2 Stage Pulsed Electric Field System
This is a 2-stage PEF system designed for products like Sugarcane, Sorghum cane & Beet Root. For the first stage, the system generates the Pulsed Electric Field for solid foods. This is aimed for puncturing the cellular structure of the food in such a way that the cells are not crushed, thereby allowing the intra-cellular liquid to come out gently. This increases the quantity (yield) of juice produced with perfect quality.
In the second stage, the juice is treated to inhibit the micro-organisms in the juice. This way the juice can be preserved by ‘minimal-treatment’ so that its original color, flavor, nutrition value and taste is maintained (unlike thermal or chemical process).
The energy is directly inputted from your electrical supply. The pulse-height, pulse-width, pulse-interval and duration are settable on the HMI. The PEF treatment chambers are constructed in such a way that, maximum energy efficiency can be derived.
In the first stage solid fruits are transferred to the reactor at a controlled rate. A programmable logic controller (PLC) controls the flow of a particular fruit to be treated. Our PLC provides a signal to the customer's control system to adjust the speed of the variable speed drive to control fruit flow at optimum level; the same is also indicated so the operator may handle this manually (if desired so).
From this stage the food is outputted for crushing & other processes that are carried out by your separate arrangement. Once the juice is obtained in liquid form, it can be fed to the second stage of the PEF machine for the quality treatment (disinfection) through VFD controlled pump (just as in SurePEF Liqvius).
All SurePEF systems are constructed for maximum safety and protection. Adequate care has been taken to insulate high voltages from ground voltage equipment. All the operation is automatic, no frequent adjustments are required.
