Yes, but the type of filling technology used in the semi-automatic machines is very important. Some filling technologies do not work well with viscous or chunky heterogeneous products such as gravity filling or pressure filling. For viscous products, we recommend a piston filling machine or a gear pump filler. They are designed to handle various viscosities, making them ideal for sauce producers who bottle a range of products from thin dressings to thicker barbecue sauces.
