ZONESUN ZS-CZI4 Manual Cream Filling Injector for Bakery Use Donuts, Churros Puffs & Cakes Paste with Precision Dosing System

Overview

The ZONESUN ZS-CZI4 is a manual quantitative cream filling injector designed for precise center-filling of pastries including donuts, churros, cream puffs, eclairs, cakes, and breads. Built entirely from food-grade 304 stainless steel (withstands up to 120°C / 248°F), it features a 5 L large-capacity hopper and a precision dosing mechanism with ±1 g filling accuracy and a minimum starting dose of 2 g. The deep-reach 6 mm injection needle delivers fillings evenly inside the product without breaking the exterior surface. Available in single, double, triple, and five-head configurations, the ZS-CZI4 scales from artisan bakeries to medium-volume food workshops, handling cream, jam, chocolate sauce, and other fluid pastes with ease.

Key Features

• 🎯 ±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.
