Precautions
1. Before using the instrument, please read this manual carefully for proper
operation.
2. It is strictly forbidden to touch the dry ice and ice blasting pipe.
3. It must be kept clean when adding dry ice, and no other foreign objects fall
into the equipment.
4. This equipment uses solid CO2 particles, and ventilation must be ensured
when operating dry ice cleaning.
5. Before carrying out the work, it is necessary to wear protective goggles, ear
muffs, work clothes and gloves.
6. Before each work, set the ice supply speed to "0" and test if condensate is
sprayed out of the nozzle.
7. Whenever the operation is not finished and you need to pause in the middle,
please first set the ice speed to "0" and then turn on the blasting gun for 30-50s
to ensure that the leftover ice is blasted out of the ice outlet tube to prevent ice
blockage.
8. In order to ensure sufficient pressure and flow of compressed air from the air
source, please choose the supply pipe of the air source larger than DN20 outside
diameter and the pressure of the air source larger than 6 bar, so as to have a
better cleaning effect.
9. To prevent electric shock, do not touch the working equipment in wet areas or
operate the equipment in the rain.
10. In the middle of ongoing work, if you encounter equipment failure, please
immediately disconnect the power.
Principle Introduction
Dry ice blast cleaning technology is based on the use of ultra-low temperature
dry ice particles, and by compressed airflow, the dry ice particles are hit by the
gas at high speed to be cleaned surface dirt. The sudden drop in temperature of
the dirt on the surface causes the surface to become brittle while causing these
extremely low-temperature dry ice gases to enter inside the cracked
contaminants. When surface dirt is hit, the dry ice particles quickly sublimation to
gas and these cracked contaminants are peeled away from the surface of the
object and removed.

Applicable fields
Dry ice blast cleaners are widely used in fields such as rubber, casting,
automobiles, ships, electric power, chemicals, printing, plastics, food,
pharmaceuticals, and aviation.
Features
Highly effective cleaning equipment can greatly increase productivity
The main function of the dry ice cleaning machine is capable of cleaning various
equipment. With this cleaning technique, on the one hand, it can avoid
production interruptions due to downtime, and on the other hand, disassembly
and damage to the equipment can be reduced, which essentially protects the
equipment and increases productivity.
1. Avoid injury to personnel from hazardous materials
CO2 is a non-toxic substance. By cleaning with dry ice instead of toxic
chemicals, we can prevent harmful substances from adhering to the equipment
for a long time, which can affect the overall operation and cause harm to people.
2. Quickly removes a variety of stubborn dirty deposits.
With the dry ice blast cleaning machine, the adhered dirty deposit can be
thoroughly removed, and also has good protection for the equipment, so as to
avoid affecting the operation and use of the equipment while being cleaned.

Equipment debugging
1. Connect the air source and power supply. Check whether the data of the air
pressure indicator is displayed normally and the power access is properly.
2. Make preparations for the debugging, including: Completely connect the
machine and the workbench; clean up the debris and dust on the workbench;
check whether the parts are loose, and clean up the objects that are randomly
placed on the machine or workbench.
3. First set to the blowing mode for trial operation from slow to fast debugging,
and then put the dry ice material into the machine for debugging if it is
determined that there is no abnormality.
Adjust the amount of dry ice blasting
1. Add the dry ice into the machine and cover it.
2. According to the degree of cleaning, turn the controller knob to adjust the dry
ice amount to achieve the best effect.
After the cleaning work
1. Turn the controller knob of the dry ice amount to the "0" position and turn on
the blasting gun for 30-50s until no water is blasted out.
2. Turn the knob controller to the cleaning mode, and the equipment will clean
the dry ice residue by itself. Manual cleaning is required if necessary.
3.Disconnect the power switch and air source, and put away the blasting gun
and accessories.
Common failures and troubleshooting methods
Common failures
1.The ice funnel in the dry ice container is blocked
2.The internal of the dry ice tube is blocked.
3.The dry ice tube leaks ice and air.
4.Poor cleaning effect, incomplete cleaning of relatively stubborn carbon
deposits

Troubleshooting methods
1. Stop working, and open the cover to see if the dry ice is overfilled. If it is too
much, take out some of the dry ice and start working again.
2. Check if the vibration pump is working, if not, please contact the manufacturer
for replacement.
3. When dry ice is poured into the funnel, it instantly takes away the air inside the
funnel, thus forming condensate clumps, which need manual assistance to move
up and down a bit.
4. During the working, the residual dry ice inside the dry ice tube and
compressed air will condense into ice because of intermittent use or stopping the
use of the dry ice machine, thus causing the dry ice tube to be blocked with ice.If
it belongs to this kind of operating condition, first adjust the ice output to 0, and
then turn on the gun switch and continue for 3 minutes, and then adjust the ice
output to 20%-30%, and then check the ice effect.
5. Examine the air source to ensure that the compressed air supplied to the dry
ice cleaning machine is free of oil and water.
6. The dry ice pipe has been used overtime, and the dry ice has been rubbing
against the pipe wall for a long time, resulting in thinning inside the pipe, please
contact the manufacturer for replacement.
7. In case the cleaning is not complete, first check whether the air source air
pressure and flow rate are insufficient. The pressure of the air storage tank in the
workshop and the working pressure of the dry ice machine are not less than
6bar, and the ice output is not less than 1.5m3/min. The air supply pipe is too
thin and too long, and the pressure drop of the pipe is too large. In this case, the
main air supply pipe in the workshop is required to be cleaned directly.

原理简介
干冰清洗技术是利用极低温的干冰颗粒，通过压缩空气的流动，干冰颗粒被气体
高速撞击被清洗的表面污垢，表面污垢突然降温导致表面脆化，同时造成这些温
度极低的干冰气体进入出现裂缝的污染物内，当表面的污垢遭到撞击是，干冰颗
粒迅速升华为气体，这些破裂的污染物从物体的表面被剥离移走。
适用行业领域
干冰清洗机被广泛的应用在橡胶、铸造、汽车、船舶、电力、化工、印刷、塑料
、食品、制药和航空等领域。

设备调试
● 接好气源、电源。检查气压指示表各数据是否显示正常，电源接入是否正常。
● 做好试机准备工作，包括:将机台完整连接，清理工作台面杂物与灰尘，检查
零件是否有松动，清理乱放在机身上或工作区的物体。
● 先打到吹气模式试运行，由慢速到快速试好后。确定无异常的情况下，再放入
干冰物料试机。
调节干冰喷射量
● 加入干冰，盖好盖板。
● 根据清洗程度，旋钮干冰量调节控制器，达到最佳效果为宜。
结束作业
● 将干冰量调节控制器旋钮至“0”,开启喷枪喷射30-50s，直到没有水分喷出。

分析及处理方法
● 停止作业，打开盖板，看是否是干冰装填过多，如果过多就将干冰取出一部分
出来，而后作业。
● 查看震动泵是否工作，如不工作，联系厂商更换。
● 干冰在漏斗填入时，瞬间带走漏斗内部的空气行程冷凝水结块，认为主动的在
漏斗正中心拿钢条 手动辅助上下活动一下。
● 干冰管堵冰是由于间歇性使用间歇性停机，而后立即停机，导致出冰管管内残
留干冰与压缩空气 导致结冰，如确实是这种作业工况1.先将出冰量调节为0, 然后
开启喷枪开关持续开机持续3 分钟，然后将出冰量调节为20%-30% ,而后在看出冰
效果。
● 排查气源，确保供入干冰清洗机的压缩空气无油、无水。
● 干冰管使用时间过长，干冰长时间与管壁摩擦，内部变薄导致，联系厂商进行
更换。
● 清洗不彻底，先排查气源空气压力、流量是否不足，工作室，干冰机工作压力
不低于6bar，量不低于1.5m3/min2.供气管太细、太长，管道压降太大，这种情况
就考虑清洗机直接作业车间主气源管道，进行作业。
