EXAIR Cold Gun Prevents Melting of Chocolate During Filling

Here we discuss about a company that manufactures chocolate products. They came out with a new line of small candies and were encountering an issue during packaging. In their process, the chocolates are formed, cooled, and packaged for resale. During the packaging process they were experiencing a problem that caused the chocolates to melt. The bags are heat-sealed along the sides and bottom. This heat was transferring from the bag to the chocolates and causing them to melt. Rather than having a finished package of individual candies, they were melting together to form one large lump. Not exactly what they are hoping to deliver to their consumers.

Fortunately, EXAIR offers a range of different products that are suitable for cooling. For this application, they utilized a Model 5330 High Power Dual Outlet Cold Gun. With the fan-type nozzle installed, they were able to cool both sides of the package immediately after sealing and just before filling the bags with chocolates.
Using only a source of compressed air, the Cold Gun and High-Power Cold Gun produces a stream of clean, cold air 50° (28°C) below your compressed air supply temperature. The Cold Gun is very quiet at only 70dBA and has no moving parts to wear out. Just supply it with clean, dry compressed air and its maintenance free! It’s available as both a standard and High-Power option, providing 2x the cooling power. Each style is available with either a single or dual cold outlet flow.

The Cold Gun is pre-set to an 80% Cold Fraction. In other words, 80% of the compressed air supplied to it will exhaust from the cold end of the tube, 20% from the hot end. This prevents the Cold Gun from freezing up during use and optimizes the gun’s cooling capacity. The Cold Gun is an ideal alternative to messy and expensive coolant mist systems. It eliminates the cost of purchase and disposal of cutting fluids as well as worker related health problems from breathing airborne coolant or slipping on wet floors. Replacing a coolant-based system also eliminates the need for secondary cleaning operations after milling or drilling.

Heavy Duty Line Vacs Within a Machining Facility

 An overseas automotive company was using six machines that milled, stamped, and punched aluminum parts.  The machining center used two machines for stamping, and the piece of aluminum was 10mm X 10mm.  The second operation used two machines to punch out a 2mm diameter by 40mm rod. The last operation was milling the edges of the surface to a specific dimension.  The curly swarf that was being produced was around 5mm in diameter by 40mm in length.

Currently they had mechanical conveyors that would dump the scrap material into bins.  The operators would move the full bins to a central dumping area for recycling about 20 meters (66 feet) away.  They used shovels to move the scrap from the bins to a larger container.  This part of the operation took time and was ergonomically unsafe with lifting and twisting.   They were making about 300grams per minute, and with a 24-hour operation, that was a lot of material.  They contacted EXAIR to see if we could help them.


To move the aluminum scrap from the machines to the recycle container, they had to travel 20 meters (66 feet) horizontally, and 3 meters (10 feet) vertically above the floor.  For this distance and the size of the aluminum pieces, I recommended the EXAIR model 152200; 2” Heavy Duty Line Vac Kit.  The through opening for the 2” Line Vac was 44mm (1.75”) in order to move the material through.  This Line Vac is made from a hardened steel construction which is very resistant to wear.  It is also designed for higher vacuum levels to convey materials at a faster rate and longer distances.

The Line Vac is operated with only compressed air to generate a Venturi vacuum, and they are very compact and easy-to-use.  The vacuum generator does not have any motors or moving parts to wear, and the inline design makes it simple to attach a hose to the vacuum and exhaust side.  The kit includes a Filter Separator, Regulator and a bracket for cleaning, controlling and mounting.  They did have to add a hopper to each mechanical conveyor to collect the scrap.  Now, the Line Vac is connected to the hopper with a hose, and the scrap material would travel to the recycle container 20 meters (66 feet) away.
