Are you filling bottles by hand and hoping the volumes come out even? The switch to a filling machine usually comes down to two questions: does the product need to stay warm and mixed while you fill, and do you want an operator to run each fill or let a conveyor carry bottles through multiple nozzles? These four fillers cover both directions, and their listed prices span a wide band.
Quick take
These four bottle fillers split into two workflows. The 30L Heating Mixing Filling Machine is a manual filler with a heated, stirring bucket, built for liquids and pastes. The other three are automatic 4-head filler setups with conveyor-fed mini lines and nozzle counts that can be adjusted from 1 to 4. If you need warm, blended product and can control each fill by hand, the manual route is the clear direction. If you want repeatable hands-free fills, focus on the automatic trio.

Product notes
30L Heating Mixing Filling Machine
This is the only filler in the group built around a heated mixing bucket. Its listed specifications include an adjustable temperature range of 0-300°C/32-572°F, a 30L capacity, and applications covering liquids and pastes such as lipstick, honey, edible oil, and beverages. The fill mode is manual, and the description lists filling accuracy as ±1% when controlled by hand. That makes it a strong match for small batches where heat and blending matter more than speed. The trade-off: there is no conveyor, no nozzle bank, and no automatic fill cycle, so every bottle moves at the operator's pace. It is also the only manual filler among the four, so if you want hands-free, repeated filling, look to the automatic group.
4-Head Automatic Liquid Filling Machine w/ Belt Conveyor
This is the costliest model in the comparison, but its title puts the belt conveyor front and center for bottle transport. The description lists a 10-500ml/0.34-16.91oz filling range, 1-4 adjustable nozzles, a diaphragm water pump, and a 110V US-plug setup. It also lists applicable bottle diameter and height ranges. The reason to choose it is the complete conveyor path built into the product name. The limitation is the price: you pay the top listed price for a 4-head automatic line with the same 10-500ml range and similar bottle-size specs as the lower-priced Mini Filling Line models. If the conveyor matters more than the extra cost, this is the one.
4-Head Automatic Liquid Filling Machine 10-500ml Bottle Filler Mini Filling Line
This model gives you the same automatic 4-head approach but adds a few details that make it easier to size. The listed bottle diameter range is 20-90mm, bottle height is 40-250mm, and conveyor belt size is 100×12×7cm, so you can compare it against your containers. The description mentions a stainless-steel mainframe and aluminum spacer for durability, and the feature list includes a three-year warranty and assembly required. The assembly requirement is the practical limitation to plan around: the machine arrives needing setup before it can run. If your bottles fall within the stated dimensions and you do not mind a little assembly time, this is a well-documented automatic filler.
4-Head Automatic Liquid Filling Machine Mini Filling Line 10-500ml Bottle Filler
This automatic line is priced within a few cents of the other Mini Filling Line model, and its description shares the same stainless-steel mainframe and aluminum spacer details. The standout detail is the sensor design: the description says sensors test both front and back to confirm bottles are in place before filling, which is a useful safeguard against chaotic filling. The package is listed as including the filling machine host, conveyor belt, and assembly accessories. The limitation is that the price gap is so small it will not settle the choice; the deciding point is whether the front/back sensor behavior and package contents match your preference.
Final recommendation by use case
Listed prices span $323.14 to $546.55, so the first cut is budget and the second is workflow.
- If you need to heat and mix creams, waxes, or other pastes before filling, choose the 30L Heating Mixing Filling Machine. It is the lowest-priced option and the only one here with adjustable heating.
- If you want a conveyor-fed automatic line and are comfortable paying the top price in this group, choose the 4-Head Automatic Liquid Filling Machine with Belt Conveyor.
- If you want an automatic 4-head line with bottle-dimension specs and assembly details spelled out, choose the 10-500ml Bottle Filler Mini Filling Line model.
- If you want a similar automatic line with the described front/back bottle-position sensors and a nearly identical price, choose the other Mini Filling Line model.
