Three 9/2 beer can filler-seamer systems which have been tested, CIP and cleaned very well will be shipped to U.S very soon. This system is consists of 9 filling valves and 2 seaming heads. But it has an amazing speed 100CPM based on 12oz can and 70CPM based on 16oz can. Of course, you can use this system for filling 19.2oz can.
This rotary canning system is with true counter pressure gravity filling system. It has pre-purge and CO2 purge functions which is to try the best to push the air out of empty can before starting to fill beer. This way reduces the dissolved oxygen number greatly. There is a CO2 blowing bubble-breaker function after filler before seamer and this is in order to push the oxygen out of bubble and CO2 will replace of oxygen. Otherwise, before the lid drops on the can mouth, there is a CO2 purging fuction, it is also an important method to reduce the dissolved oxygen number.
Rotary(high speed) VS Inline (low speed):
Many microbreweries would like to add a small (low speed) and compact canning system at the beginning stage because finance and area are issues. That will be the best and fast way for microbreweries to start. One thing which most starter will ignore is the beer oxidation. Some customers told me that why canned beer has the oxidation taste after packed in a short time. They were very strange to it and could not find the reason. I have to say that they brewed great craft beer which has a really fantastic taste before packing. They have a full of knowledge making beer but they do not know how to pack. Making beer is like left brain of head, and packing beer is the right of brain. If you can control left and right, that will be fantastic. I asked them which packaging machine they are using? They told me that low speed inline can filler and seamer or rotary canning system with carbonated drink filling valves. That is the key point to cause oxidation taste because beer is very easy to be oxidation if he opens to air or touches air. Inline canning system is with long filling valve and low speed, it will cause the beer opening to the air during filling and transferring from filling to seaming. As we know, we do not need to consider the oxygen too much if we filling carbonated drink. The filler bowl has no pre-purge and CO2 Purging-Pushing-Air functions, so all empty can air will be pushed into the beer bowl. It is not difficulty to think that beer from the bright tank to the bowl and then contacts more airs which are from empty cans. After reading this, you should be very clear why some canned beer tastes oxidation. However, if you can finished canned beer (inline system) after packed in a short time. That will be no problem.
High speed rotary true counter pressure gravity canning system can resolve beer oxidation taste issue. High speed means that it will reduce the air contacting time during the whole process of filling, transferring and seaming. Beer bowl and filling valve has pre-purge and CO2 Purging-Pushing-Air functions means that most air in empty can will be throw out of can. As said at the beginning, there are CO2 bubble breaker and Under cover CO2 device functions. If it is allowed, I suggest you to select High speed rotary true counter pressure gravity canning system because it makes your packed beer fantastic. Here are some indexes for your reference: Oxygen pick-up should be less than 40ppb and TPO is between 50 to 100ppb.
