• Ware is placed in racks and passed through the
machine via a reciprocating conveyor or pegged
conveyor belt.杯筐/餐具通过往复式杯筐传送装置/传送
带送入机器内部
Single Tank Machines单缸洗碗机
• Wash and rinse timers are generally fixed by the
manufacturer清洗和喷淋时间基本上由生产厂商确定
– Wash Cycle: 45-180 secs主洗时间: 45-180 秒
– Final Rinse Period: 7-15 secs喷淋时间: 7-15 秒
Multi-tank Machines多缸洗碗机
• Contact time is determined by conveyor/belt
speed. Some machines have up to three speed
choices; for light, medium or heavy soils接触时间由
传送装置或者传送带的速度决定。一些机器有三种速度的
选择,分别对应具有轻度污垢,中度污垢和严重污垢的餐
具.

Chemical清洗剂
• The detergent dispensed into the wash
tank is formulated to:进入洗碗机水槽的洗
涤剂主要作用为:
– Break down grease and food soils将
油脂和食物残留与餐具分离
– Suspend soils and prevent them
from re-depositing on ware将油污悬浮
于液体中,防止其再次沉积在餐具表面
Mechanical Action机械力
The Wash Arms清洗臂
• Deliver powerful spray of detergent
solution onto ware to dissolve food
soils将洗涤剂溶液强劲地喷射到餐具上分解
食物残留
Final Rinse最终喷淋
• Rinses detergent from the ware清洗餐
具表面上的洗涤剂
• Applies rinse additive to promote
faster drying用快干剂加快干燥速度
• Rinse temp of 82 C+ sanitizes the
ware喷淋温度在82度以上消毒餐具

•
Pre-wash预洗
Softens/removes grease and gross food soils.
Temperature should be less than 50°C将油脂和食物残留
软化并去除。温度应该低于50度.
Main-Wash主洗
Detergent and hot water removes food soils.
Temperature should be between 60-65°C洗涤剂和热水
去除食物残留. 温度应该在60-65度之间.
Power-Rinse强力喷淋
Removes most of the detergent solution from ware.
Temperatures should be between 70-75°C去除餐具表面
大部分的洗涤剂溶液,温度应该在70-75度之间.
Final Rinse最终喷淋
82°C fresh water final rinse removes any remaining
detergent residual from the ware. A small amount of
rinse additive is injected into this water to promote
faster drying and spot-free results 82度的清水最终漂洗
去除餐具表面所有的洗涤剂残留液。少量的漂洗剂同时注入,
提高餐具的干燥速度和餐具的光洁效果.
Direction of Travel传送的方向
Each tank must get
progressively hotter in
order to build up heat in the
ware as it passes through
the machine. It is this build
up of heat that allows fast
drying of the ware as it
exits the machine!餐具在洗碗
机内部逐步传送过程中,每一个
水槽的温度逐渐上升,以便让餐
具的温度逐步上升。正是这种温
度逐步上升产生的热量可以使在
洗碗机内部的餐具能够快速的干
燥!
