Setting higher standards in food safety, egg quality, cleanability, sanitation, and performance with the OptiGrader series for advanced egg grading.
The OptiGrader 450 handles 162,000 eggs/hour (450 cases/hour) at full speed and only operates in-line. The details in the OptiGrader series design make a clear difference in machine efficiency and operating costs and become visible after challenging seven-day-weeks.
Configurable to fit into the same footprint as the older 300 to 400 cases/hour (108,000 to 144,000 eggs/hour) machines. It can be installed with used machinery or a different choice of packers, offering you flexibility in your investment.
We recommend using sustainable egg packaging from 
To further reduce the time a dirty egg is in the grader, SANOVO can move the dirt return before the scales in the transporter to remove dirts right after the leak drop. This will provide an empty space after crack detection to drop bad cracks & small peewees to continually provide a higher quality in the final pack to the consumer.
The packer is totally wash down and easy to clean.
New transporter kit has CIP over scales, crack detector and all drop gates.
The UV light kit will further sanitize the first part of the transporter to reduce the risk of cross contamination.
The SANOVO Reservoir Brush Washer is a compact design, that will thoroughly clean and sanitize the received brushes used in the gentle transfer to the packing lanes.
The roller entry conveyor transports the eggs towards the weighing and insert section. Material of the rollers has been specially chosen to withstand numerous cleaning products.
To reduce cleaning time and improve the sanitation level, a CIP system can be added, from the first roller towards the insert mechanism. The shape of the rollers gives stability, allowing camera-based detection systems to create an optimum performance.
The design minimises horizontal surfaces to reduce dirt accumulation.
Our exclusive egg conveyor can send any egg weight or second quality egg out of the grader before the transfer to the chain conveyor.
It allows the off-grades and overweight and underweight eggs to be packed without being transferred into the four-row chain conveyor. From this conveyor, the off-grades can also be send directly to a Breaker or Farmpacker.
The SANOVO Accumulator orients the eggs into 12 or 18 rows with the highest filling rate in the industry.
Belt material has been carefully chosen to minimise the contact surface, while the open construction allows thorough cleaning. Optional CIP cleaning is available.
The high performance dirt detector with adjustable sensitivity makes use of an advanced full colour camera vision system that identifies dirt down to 1.0 mm2.
Detected dirty eggs can be sent back to the egg washer or sent to a packing lane.
The leak detector can be installed to reject eggs before the egg washer, reducing water contamination and antifoaming chemicals.
It can be installed after the washer to reject leakers before travelling under the high velocity air drier, reducing the risk of contaminating clean, first quality eggs, or after the drier in tandem with the dirt detector. Rejected leakers will be dropped into a bin or optional auger and centrifuge.
The system is making use of laser light technology placed underneath and away from the egg flow. False rejects are minimised, and shiny wet surfaces do not influence the detection rate.
A digital, dynamic, stable egg scale weighs each egg with a readout of 0.1 gram and tests itself for recalibrations between each egg.
Our Egg Scale and entire infeed and transfer insert is washdown with an open sanitary design.
The scale is mounted under the egg for maximum stability, observation and ease of cleaning. Calibrating the 12 or 18 weighing scales can be done within minutes. Fragile moving plastic parts are not part of our design.
The advanced washdown Crack Detector has no moving mechanical or electrical parts. It is not necessary to constantly sense and adjust for the continual variation of egg weights.
This robust system converts the digital signals into multiple crack categories. The operator can determine what level of crack should go to various undergrade categories.
There are no delicate parts or complicated time-consuming cleaning requirements.
With color grading, batches can contain both brown and white eggs. The grader will recognize these eggs and will send them separately to a packing lane, so only a specific color is put into a pack. By color detection, a batch of mixed eggs are available on the infeed and only specific colors are on the lanes.
This optional functionality is possible with the dirt detector and assist to get homogenous color output on your final product. Fully automatic the grader will isolate unwanted egg shell colors or even go further create classes with a unified shade of brown eggs into a pack.
The UV system uses ultraviolet technology to reduce contamination and bacteria on the shell surface of the eggs before weighing and packing.
Entry guards ensure that the UV-C light stays within the system. Being detachable, it makes cleaning very easy. If the system is tilted, the safety switches automatically shut down the UV lights to ensure a safe environment for the operator.
Optional for non-egg washer installations.
The roller cleaning system operates in accordance with the infeed rollers and is located under the roller conveyor. Three brushes run and sweep the rollers during operation.
A variety of takeaway conveyors lengths are available to meet individual egg packaging requirements. Egg printing, carton labelling, dating and 30-egg tray stacking is all available. Takeaway conveyors are designed to meet the needs by further automation with SANOVO End-of-Line Automation.
The most reliable transfer from 12 or 18 rows of eggs into the chain conveyor in the industry. We have eliminated compound cantilevered motions, delicate machine components and fragile swing arms with critical timing, sensitive to egg weight variations.
The overhead four-row egg conveyor momentarily stops while 48 or 72 eggs are gently lifted into the egg carriers during the right- or left-hand transfer.
The new generation, low profile, variable speed carton closer adds reliability and flexibility to the packaging line.
The end alignment, denesting, packing, egg printing, and closing are all on the same side of the system. The double denester feature allows one trained machine operator to control all the packer functions over 700 cph. There is no need for the operator to crawl back and forth under the machine to manage, observe or help the packing functions.
Detected blood eggs can be programmed to be ejected out of the egg carrier chain at the end of the grader, or sent to any lane.
The whole system is placed above the egg carrier chain and can be tilted for easy cleaning, which makes it very accessible. Intelligent software recognises the difference between brown or white eggs and adjusts the parameters automatically.
The four-row egg carrier chain releases each egg individually by weight and category into soft brushes, the most gentle transfer in the industry.
The brush receiver eliminates a multiple series of critical high speed transfers, risking small hairline cracks that can open after transport and in-store handling. There are no critical transfers or timing issues.
Every six packing lanes are equipped with large screens on the back and front as standard.
The information screens provide real-time information of the grader speed, printer texts and current grader status, in order to minimise response time and maximising your productivity.
A revolutionary denesting system grabs the inside of the carton or tray with 32 needles and places it directly on the packer lane, increasing reliability.
The packer eliminates pen conveyors and carton jams before packing. Denester adjustments on pack changeover have been reduced, and the denester is manufactured as a refined, accurate machine. A second denester for each packer is available to eliminate changeover down time, doubles the denester carton storage, reducing labour and acting as a backup to damaged or poor quality packaging.
Our Special Denesters for customers including 24- and 36-egg lidded carton denester. All available without the need to extend the packer base and electronics. Customised denesters are available on request for your special packaging needs.
The OptiGrader touch screen controls the system and the whole process with large overhead displays for all grading room operators to observe.
The touch screen is ICON-based and a Windows operating system. Accessibility of data and user friendliness go hand in hand.
The menu structure can be determined and altered by each operator, creating the perfect user program for the packing station. Only four inkjet printing heads are required at 700 cases per hour / 252,000 eggs per hour. Traceability software to keep track of every egg that enters the grader and packer is available.
