Why Choose the ZS-CZI4?
-
🎯 ±1 g Precision Dosing — Consistent Fill Every Time
The precision quantitative dosing mechanism delivers ±1 g filling accuracy from a minimum dose of 2 g, ensuring every pastry receives a consistent, controlled amount of filling — eliminating the over-filling and under-filling that occurs with manual piping bags. -
🍮 Deep-Reach 6 mm Injection Needle — Clean Exterior, Full Interior Fill
The slender 6 mm stainless steel injection needle penetrates deep into the pastry center, delivering filling evenly throughout the interior without breaking, tearing, or marking the exterior surface — maintaining the finished appearance of premium bakery products. -
🧱 5 L Hopper — ~50 Fillings Per Load
The large 5 L hopper holds enough filling for approximately 50 donut or pastry injections per load, reducing refill interruptions during production and supporting continuous workflow in busy bakery and food workshop environments. -
🛡️ Full 304 Stainless Steel — Food-Safe up to 120°C
All product-contact surfaces are fabricated from food-grade 304 stainless steel, providing corrosion resistance, easy cleaning, and heat tolerance up to 120°C (248°F) — meeting food safety standards for commercial bakery and food production environments. -
🔢 1 to 5 Head Configurations — Scale to Your Output
Available in single, double, triple, and five-head versions, the ZS-CZI4 scales from single-operator artisan use to multi-head parallel filling for medium-volume bakeries and food workshops — multiplying output without requiring additional machines or operators.
