The development of packaging and filling technolog

The development of packaging and filling technology of tinned beer (Part 2)

modern beer technology widely uses computer recognition systems and digital display instruments to assist in mechanized filling operations to ensure that beer quality is not affected in the filling process. The hearing remover can automatically detect the following manufacturing defects of the cans: oil, liquid, deformation, foreign matter, and odor, and remove the unqualified containers from the line

the inner wall of the earphone is washed with clean brewing water after liquid detection before washing

the air earphone is flushed with CO2, prepared for pressure, and then filled with wine; After the wine filling is over, it will be subject to pressure relief, bubble breaking, and then sealed and capped. The tolerance of 355ml internal volume should be controlled within ± 8ml, and CO2 should be within 2 Between 85, og is 10 0, the average control of TPO is lower than 134ppb. Wine filling and sealing are closely linked, and KHS is the majority of machine suppliers

heuft liquid level detector is used to detect the volume in the ear, automatically take samples, and record the number of filling defects of each wine valve

beer sterilization process is divided into three parts: heating up, 62oc sterilization temperature and cooling down. Improper sterilization affects beer flavor, and the quality indicators that should be controlled are: PU (), MPT (141 ± OC), BOT ≤ 27oc

the liquid level detection after sterilization is controlled by a filtec weight meter, which automatically picks out the tinned wine with insufficient liquid level

printing defects mainly include fuzzy printing, missing printing, wrong printing and unequal printing positions. Vediojet is the main inkjet machine suitable for small character high-definition inkjet

style renovation

for canned applications, foreign countries have developed various forms of packaging. If it can be used in the domestic market, it will consolidate and improve the high-end status of tinned beer, promote sales, protect the environment and consumer safety. The packaging forms with innovative significance mainly include:

◆ can surface embossing: a kind of special-shaped cans, add an embossing machine in the forming process section of the cans, and make the surface of the cans become uneven and personalized by installing different molds. You can also use special ink to print embossed visual effects, but there is no convex and concave feeling when holding the can

such as trim strips or other decorative components in the central console or instrument panel ◆ temperature change effect: use low-temperature variable temperature sensitive ink to print beer patterns or logos, and start to display within a certain temperature range, which can not only remind consumers of the best drinking condition, but also play an anti-counterfeiting role

◆ film printing: PE film flexographic printing is adopted and then attached to the white tin. The effect is the same as that of metal printing, but flexographic printing is bright, flexible and environmental friendly

◆ sot environmental protection cover: sot refers to that the pull ring on the hearing cover will be hidden and attached to the cover after the cover is opened, so that the cover can be recycled together with the tank body, and at the same time, consumers can be protected from accidental stabbing by the pull ring

◆ dust prevention on the cover: due to the continuous complaints of consumers about the hygiene of the cover of tinned wine, a dust-proof composite film on the cover is sealed on the tank cover after filling and capping to prevent dust pollution

◆ aluminum bottle and can: the aluminum bottle and can invented in Japan is to make the metal container adapt to the glass bottle filling line. The lower part of the bottle is in the shape of a tin, and the upper part has a bottleneck. For surface printing, a preprint film sleeve is attached to the surface of the bottle

◆ paper cans: the can body is made of paper and aluminum foil, and the can cover is made of plastic with pull rings. Due to pressure resistance, it is not applied to beer packaging at present

◆ combined packaging: various forms of tins combined packaging include hicone plastic tape, shrink film wrapping, die-cutting cardboard wrapping and die-cutting cardboard connector. If the order quantity is large, machine packaging can be used, and if the order quantity is small, manual packaging is more economical

◆ handhole boxes: handhole boxes with 12, 18 and 24 cans are opened on the side of the carton to facilitate elimination 3 Deformation measurement sensitivity of the experimental machine - the displacement rate of the relative measured change of the sensitivity instigator is extracted when the user purchases the whole box. In order to enhance the strength of the hand hole, the load torque of the general servo machine is often required to change continuously and gently. A kind of hot soluble PVC fabric with a surface layer is used, which is bonded in advance on the corrugated board line of the carton factory

food canning trend

according to the news of a technical meeting at the packaging exhibition/food processing machinery exhibition, EZO is at the forefront of this trend. Canning is a practical container for food, and with an easy to pull lid, there is no need to use a can opener. Cost will be a problem, but supporters of easy cover cite research findings that consumers are willing to pay an extra 6 to 8 cents per package

"60% to 65% of European canned foods use easy pull lids, which is 80% in the German market," said Jeff deliberty, marketing manager of Silgan closures, located in Downers Grove, Illinois, USA. "in the Asian market, EZO penetration is about 60%

but in the U.S. market, the share of easy to pull lids only accounts for 35% of cans. Deliberty predicts that this figure will reach 60% in 2008. He predicts that the key areas of transformation will be pet food, soup/chili/pasta, and fruits and vegetables

while most of the discussion still focuses on the rigid metal pull covers, the new generation of easy pull covers, including peelable foil, some of which can be processed in ultra-high pressure containers. They can be made into irregular shapes, and the pattern on them can be comparable to the can body label

new technologies currently being discussed include:

◆ the "spike" can is vacuum packed and resealable before opening

◆ square cans, well packed and have a good shelf publicity effect

◆ self heating cans can realize small-scale exothermic reaction

◆ spiral top cans

◆ it can be used as a can for heating steel bowls in a microwave oven at the same time

the centerline of the sample should be as close to the steel surface as possible
