Q: How does the liner work? Why?
A: Beck block liners are carefully designed to absorb a certain amount of water and when frozen this liquid forms a complete oxygen barrier. The complete oxygen barrier protects your product like no other material from freezer burn and dehydration. This also allows for a solid and completely uniform block of fish without water or holes.
Q: What is so special about a block of fish? Why not some other product forms?
A: Blocks allow customers to cut and bread and/or portion to exact measurements. This is of utmost importance to fish burger retailers as they want exact dimensions and perfect quality in every burger. This is the same for fish stick, fish finger producers. With the fish being frozen within 45 minutes you can also ensure the highest quality product.
Q: How can you tell the inside of the liner from out?
A: The outside of the liner is usually a darker shade of brown than the inside. Also, the outside has a smooth finish and the inside has a dimpled feel.
Q: How do I put a liner in a frame? Where do the flaps go and why?
A: The bottom of the liner slides into the freezer frame. The liner in the frame is filled with fish then the lid is folded over and the front flap tucked in between the outer layer of the liner and the frame. Corner flaps should never be on the inside of the liner as it sits in the frame. Beck liners are designed to automatically place themselves correctly in the the liner.
Q: How important are the frames?
A: Beck aluminum frames are unsurpassed in their ability to produce a perfect block. Dimensional tolerance is ½ a millimetre. The frames form the block into the rectangle when they are placed into a block freezer. Beck frames are strong and hold up against pressure from the plates and the fish.
Q: How much fish weight do we pack in a liner? Do species vary?
A: Yes, species vary due to density. Pollock weight going into a liner is usually about 16.7 lbs.
Q: How much time between packing a liner and freezing is OK?
A: 45 minutes is the maximum.
Q: How do I differentiate products? What works to write on a liner?
A Beck offers custom printed liners. You can differentiate by color. We can print logo, product types and we can make check boxes. Grease pencils are used for marking on the blocks. Also, there is a laser print system that does work. It is difficult to write on the outside of a liner because the liner is coated with wax.
Q: Can I make blocks without an ejector?
A: Yes, but it is not recommended for mass production. For samples you can line the inside of the frame with food grade oil. This will allow the blocks to more easily release from the frames. Beck ejectors are a cost effective way to remove blocks from fames.
Q: What kind of freezer should I buy? What size?
A: There are various producers of plate freezers both new and used. Contact your Beck representative for a producer near you. Plate freezer size depends on the amount of product you want to produce. Stations are the number of plates in a plate freezer. Plate dimensions relate to the number of frames you can put onto the usable plate surface.
Q: How do I get the frames out of the freezer without damaging them?
A: Hot gassing in the plate freezer is the best way. Some use a bar that has a plastic (food grade) end that is used to push the frames out. Some use a hooking bar if they need to pull the frames towards them.
Q: What can we do to take better care of our frames and bottoms?
A: Upon defrost do not hit the aluminum frames with a metal bar to release them from the plate freezers. Do not throw the frames at any time in the process.
Q: Are my frames any good or do I need new ones?
A: Beck has available frame checkers that will show you if your frames are out of tolerance. Typically frames bow out on the sides requiring more products to produce a perfect block.
Q: How many liners can be put on a pallet?
A: Liners are packed anywhere from 3,000 to 3,200 to 3,400 to 4,000 pcs depending on customer requirement.
Q: What storage temperature do you require for storage of the liners?
A: We have the same restriction to storage temperature as the stable temperature of the liners. It is very important that the temperature is not higher than 35 °C.
Q: My blocks end up with an uneven surface - why?
A: Overfilling will lead to crowning block surface – check final weight of block after freezing. Blocks placed on freezing plate waiting for too long for other products to be loaded can lead to an uneven surface because the block will begin to freeze from bottom up so when finally pressure applied freezer is unable to squeeze the material into corners and flatten the surface. Also, pressure applied too late in the plate freezer and insufficient pressure can lead to an uneven surface.
Q: The liner burst at the edges - why?
A: Typically busted edges are due to a frame that is of wrong dimension or out of shape – check frames for correct dimensions regularly and see to that you buy frames from trusted source. Liners that have been soaking for too long can lead to busted edges when pressure is applied.
Q: Why do we not seem to get contact between top of block and the liner? Why do we see icing on the block?
A: The frames might be of wrong dimensions why you will have to overfill the block to make up for the difference. This, however risking that the liner will burst.
