The CM Machine Services PADDLE MIXER RX-600 is a robust industrial mixer designed for various food processing applications, particularly for mixing batters in the production of meat, canned meats, vegetables, fruits, and sauces. It features a compact, self-supporting welded construction, with all parts in contact with the stuffing and exterior surfaces made of acid-resistant stainless steel to ensure hygiene and durability. The machine can optionally be equipped with a loading pillar.
Function Description:
The RX-600 paddle mixer is engineered to efficiently stir stuffing using two intersecting bladed stirrers positioned at different heights. These stirrers offer a variable direction of rotation, allowing for flexible mixing processes. The mixing shafts' speed can be manually controlled within a range of 5 to 48 revolutions per minute (r/min). The machine is designed to integrate with an optional loading pillar for automated loading.

Usage Features:
The machine's control panel (Fig. 4) provides comprehensive control over the mixing process. It includes:
- Inward and outward rotation buttons for mixing shafts.
- A variable speed potentiometer for adjusting mixing shaft speed.
- Lifting up/lowering down controls for the integrated loading pillar (if option is present).
- A STOP button and a green light indicator for machine operation.
- An emergency STOP button on the right side for immediate shutdown.
Safety in Use:
Operators must be fully aware of potential threats and the operation of protective devices.
- Always follow the instructions and recommendations in the user manual.
- Only authorized personnel should perform troubleshooting, repairs, or maintenance in standby mode.
- All work, including troubleshooting, repairs, maintenance, lubrication, and cleaning, must be performed with the power supply off.
- Modifications or bypasses of protective devices are strictly prohibited as they compromise machine safety.
- It is forbidden to walk on the machine, its top flap, or any other components, or to grab actuators.
- Hands must not be placed under the ejection flap.
Improper Use:
The paddle mixer is not designed for mixing frozen meat at temperatures below +2°C, boned meats, hard products, or flammable liquids.
Mixing Cycle Steps:
- Close the stuffing ejecting flap.
- Place an empty stuffing trolley below the ejection flap.
- Open the tank cover.
- Load stuffing into the tank manually or using the loading device.
- Close the tank cover.
- Initiate the mixing process.
- For unloading, select the convergent direction of paddles. Open the ejector flap using the lever (ensure the lock preventing accidental release is disengaged).
The maximum level of mixed stuffing must not reach 100mm below the top edge of the tank border.
Maintenance Features:
Daily Maintenance:
Before the first startup each day, the effectiveness of safety and protective devices must be checked:
- Tank top cover switch: Mixing paddles should not operate when the cover is open.
- Stuffing ejection cover switch: Mixing paddles should not operate when the stuffing trolley is absent.
- Chamber drive shaft door switch: The machine should not start when the door is open (functions as an emergency button).
- Emergency button (red "mushroom" button with a yellow ring): All drives switch off when pressed. It latches when pressed and can be unlocked by pulling. It affects control voltage but not the main circuit.
- Main switch: Turning the knob from "I" to "0" position cuts off machine power supply.
ATTENTION: If any safety or protective device fails, do not use the machine. The defect must be removed by a specialized service. Unauthorized changes to safety devices void the manufacturer's responsibility and guarantee.
Lubrication (Table no. 3):
- Gear motor: Lubricant replacement according to manufacturer's instructions (Transmission oil recommended by gear motor producer).
- Chain: Lubricate every two weeks (about 100 hours of action) with graphite grease.
- Drive shaft bearings of mixing paddles: Covered, do not require lubrication; replace when clearances appear.
Cleaning and Hygiene:
The machine is made entirely of stainless steel to prevent product residue retention and bacteriological risk. It stands on four legs, spaced from the ground, allowing for thorough cleaning underneath and around it. Proper leg adjustment and mixer positioning facilitate washing and drying of the tank and mixing paddles.
Cleaning should be performed using cleaners for stainless steel recommended by reputable manufacturers.
- Mixing shafts: Clean daily after work from meat and fat remnants. Clean agitators with the tank cover open, only with proper operation of the proximity switch, and when power is turned off.
- Mixing tank: Wash daily after work with warm water and detergent, then dry (sponge rubber). Clean and wash only with the power off.
- External surfaces: Wash daily after work with warm water, strong stream of hot water. Avoid direct contact of water with electrical components (control panel).
Washing and Disinfection (Table no. 4 & 5):
- Alkaline disinfection: Coat surfaces evenly with foam, leave for 15-20min. Clean with brush, rinse with water flush.
- Acidic cleaning: Change environmental pH and remove mineral deposits once per week. Proceed as for washing with alkaline agent.
- Additional disinfection: After acidic foam washing, periodically coat surfaces evenly with disinfectant solution, leave for 15-20min, rinse with water flush.
- Surface care: Periodically polish and care for surfaces. Spray surfaces evenly with preparation and spread with a soft cloth.
Periodic Inspection, Adjustment, Repair (Table no. 6):
- Checking for leaks in the chamber between the tank and the drive shafts chamber: Daily visual inspection. When replacing O-rings, fill space with food-approved grease.
- Tightness of gear motor: Monthly visual control through the window in the gear motor body; add oil if needed.
- Chain tension: Monthly check. Clearance midway between the two sprocket wheels must be approximately 5 mm. Adjust by turning the nut on the bolt.
- Replacement of reversing wheel bearing and chain: If needed, disassembly and assembly of shafts should follow Fig. no. 5.
Warranty Settlements:
The manufacturer provides a 12-month warranty from the date of delivery for trouble-free operation. The warranty does not cover damages resulting from:
- Mechanical issues.
- Improper use.
- Interference with the machine's construction through self-modifications.
- Bypassing security features.
The warranty also does not cover consumable replacement parts such as seals of ejection flaps, O-rings, bearings, and sliding bearings. The guarantee is valid only when operating in accordance with the Operating Instructions and warranty rules of conduct.
