Project Review of Yantai Beer Asahi (Qingdao)

Nov. 2015

Brief Introduction

A Lehui Nanjing made 40,000 BPH draft beer packaging

line and other main equipment for pasteurized beer

production have been delivered to Tsingtao Asahi’s

Yantai Brewery in March, 2015. Main equipment includes a

double-end bottle washer, Pneumatic-electronic filling

valve steri le f i l ler , a CIP system, an energy-saving

pasteurizer and so on. The packaging line has been put

into operation smoothly since July 19, 2015.

Double-end Washer

Lehui double-end bottle washer adopts Belgium Crown-Baele technology. Crown-Baele is a filling & pack-

ing machine manufacturer in Belgium with more than 100 years of experience in manufacturing and

service, and it has been the industry’s No.1 brand as always.

The client list of Crown-Baele includes: Heineken, Carlsberg, SAB Miller, Castle group, AB-InBev, Coca-Cola

and other valuable Belgian local enterprises.

Crown-Baele bottle washer technology helps Lehui increase washer capacity up to 12,000 BPH , and reduce

power consumption by 60-70%, water consumption by 20-30%, steam consumption by 50-60%. Reliability

of the washer has been significantly enhanced.

Advantages of Lehui washer are as follows:

Triple pre-spray design reduces bottle breakage, prolongs caustic useful time and aids continuous

production.

Caustic tanks adopt single-loop design, which enables fast warm-up and flexible temperature

control. With balanced main chain design, power required for driving the chain is effectively

reduced.

Chain rail adopts floating design, which is easy to repair & replacement.

Reliable rotate-sprays align well with bottles , easy to maintain and clean.

Label extractor adopts drum design with good label remove effect. With label conveyor device

and hydraulic presser, discharged spent label contains less moisture and is of less volume and

easy to transfer.

Double-end Washer

Special duckbill type bottle pocket can adopt different pitch according to bottle diameter. All metal

bottle pocket and carrier design effectively guarantee use life and strength.

Bath tanks are designed with round transition from wall to bottom. A sloped bottom to aid thorough

discharge.

Pre-rinse, final-rinse boxes and top of caustic bath are all stainless made to prevent corrosion.

Multi-drive system, different from cross-coupling of mechanical transmission, greatly reduces main

drive power consumption, and is automatically controlled.

Between caustic #1 and caustic #6 there is a PHE system, which effectively reduces thermo-energy

consumption.

Machine surface & caustic tank bottom are insulated,for safety, good looking and energy saving.

EP-filler uses Lehui-developed K-type pneumatic-electronic filling valves. This technology

combines convenience/flexibility of electronic filling valves and stability/durability of mechanical

valves, with high fill accuracy.

Lehui EP-Filler adopts isotonic pressure filling principle. Fill height is controlled by vent tubes.

Multi-counter pressure and vacuum are available according to clients’ specification.

K-type filling-valve comes with a simple structure which is easy to clean. Valve stem, vacuum

valvesand pressure relief valves are bellows sealed, preventing environmental bacteria from

infecting product when valves operate. K-type valve is suitable for filling draft beer.

Filler

Filling steps are precisely controlled by PLC. Change of filling process can be achieved by simply call-up

of pre-set parameters stored in the computer. Filling parameter is not affected regardless speed. At low

speed filling, the vacuum, counter pressure and fill height stay the same as at high speed. Pressure only

relieves when filling is complete.

K-type filling valve has shorter vacuum channels. As a result, there is less resistance for thorough

vacuum and less dissolved oxygen pickup.

Lehui EP-filler adopts separated transmission which is synchronized via variable frequency drive. Two

gear motors adopt SEW synchronous with encoder tracking technology. The motor for filling station is

driving while the motor for crowning running passively. Filler speed is controlled via a variable

frequency motor. Height adjustment is motorized.

Filler

All part which would contact with filling media is made of SUS304 stainless steel for food hygienic reason.

Lehui EP series fillers adopt filling & capping station mono-block design. Adjustment of filling process is

easily accomplished via HMI. Height adjustment of beer chamber, crowner can be accomplished via HMI

as well.

High pressure foaming device adopts imported piston pump & heater witch are stable and reliable.There

are low pressure and low temperature alarm systems installed. An automatic proportional (6 levels)

control ensures filling pressure is synchronized with filler speed to reduce bottle neck air, reduce oxygen

pick-up.

Filler

Stainless steel plates are installed between filling valves. Lehui EP fillers are equipped with bottle burst

monitoring device as well as multi-angle jetting function. The angle of jets can be manually adjusted.

Beer chamber is equipped with a separated pressure relief cavity. Pre-exhausted foam is centralized to the

relief cavity before a bottle exits. Counter pressure foam collection is under counter pressure, which

reduces environmental pollution.

Lehui EP-filler adopts SIEMENS SS vacuum pump, with a circulation water tank made of SUS 304 stainless

steel and an automatic temperature replenishment system.

EP-filler valve array adopts hygienic design, with double-seat valves, online steam sterilization, online

dissolved oxygen meassuring, OG and CO2 measuring and so on.

Lehui EP-filler adopts centralized lubrication system. Lubrication interval can be set accordingly. A foam

cleaning system is included and the operation can be set via HMI.

Pasteurizer

Lehui Pasteurizer adopts tunnel spray, double-deck, and net chain driving. This machine has 12

temperature zones and each zone is equipped with a low power pump. A large diameter plastic nozzle

spray system is installed, in both upper and lower deck to achieve uniform spray and to eliminate blind

spots.

Lehui Pasteurizer features a centralized heating design, a lowly positioned pipeline system with excellent

thermal performance, low noise and easy to maintain and repair. It is also equipped with a broken glass

remove device to prevent glass pieces from blocking the sprays nozzles.

Lehui Pasteurizer has equipped with temperature control and automatic PU control dual control mode,

and two modes can switch alternatively. PU control mode also has an automatic shutdown function to

automatically adjust spray temperature of hot zones. Over the length of downtime it automatically adjusts

temperature of hot zone, to ensure PU control within a certain range, so as to ensure uniform

pasteurization.
