The universal solution to the automatization of the soft-drink production process is found in the BAS02 Measurement System which not only analyzes the product on the line, but also performs automatic control, recording, remote control, data collection and processing functions.
The BAS02 analysis system includes:

  • IB05 analysis unit (Brix / Diet /CO2 , optionally alcohol and oxygen)
  • Brix controller (field)
  • CO2 controller (field)
  • Recorder or printer for data collection (field)
  • Remote display
  • Remote control and MULTILAB IV
  • Data acquisition

IB05 Analysis Unit
The IB05 Analysis Unit is the basis of the BAS02 system. It is the result of Maselli's search for new technologies to meet the ever-changing needs of the soft drink industry. In fact, as a result of faster and more sophisticated lines, the need for consistent product quality and the rising cost of raw material prices, a close control of the produced soft drinks' basic analytic parameters (sugar or sweetner levels, CO2 volume) has become indispensable.

To meet this need, MASELLI MISURE has a long history of offering solutions aimed at satsifying two basic requirements:

- constant quality
- containment of production costs

The IB05 analysis unit is the system's first element and meets all basic requirements for soft drink production control by combining the following functions:

analysis (Brix / Diet /CO2 , optionally alcohol and oxygen)

alarms

data transmission

The IB05 analysis unit includes:

A) UR21 Refractometric Analyzer
B) UC04 Carbometric Analyzer
C) US01 Ultra sonic device (Alcohol analizer)
D) UX01 Oxygen Analyzer
E) sealed, stainless steel control panel
F) circulating pump
G) hydraulic circuit (piping)

All components are interconnected and mounted on a self-supporting stainless steel frame. The hydraulic circuit has quick-coupling tri-clamps. The unit is designed to detect sugar or sweetener concentration levels and CO2 content of the product being analyzed, alert the operator and transmit the relevant data to the remote control or data acquisition systems.

The Functions
Brix Analysis
The UR21 Refractometer microprocessor version detects the Brix degree. A switch on the receiver makes it possible to select the Brix field between 5-15 for sugared and 0-2.000 for dietetic soft drinks. The CCD optical sensor guarantees high-precision and repeatability without drift over time.
The optical system is insensitive to the measuring lamp's intensity
fluctuations in to the photocell's aging, or prism's fouling. The
refractometer is also not affected by CO2 or air bubbles that can disturb density readers.

CO2 Analysis

The CO2 level is determined by the UC04 Carbometric Analyzer on the basis of the correlation between this parameter and Henry's Law saturation pressure.
In the measuring chamber where the product being analyzed is sampled, a mechanical shock causes pressure to rise until the saturation pressure is reached. The instrument detects the saturation pressure and temperature in the measuring chamber and then, applying Henry's Law, calculates the volume of CO2 present in the soft drink. This measurement cycle is repeated two-to-four times a minute.

Alcohol Analysis (optional)

The alcohol content is measured combining the data obtained by the Refractometer (UR21) and an Ultra Sonic device (US01). In order to determine the sonic velocity a transmitted pulse is sent through the liquid and the time is measured till this pulse is recognized by the receiver. This time measurement precisely gives the sonic velocity, which is intrinsically related to the concentration.

Oxygen Analysis (optional)

The dissolved O
2 content is measured through the UX01 Oxygen Analyzer. It's based on a standard amperometric method, and it combines an Electrode (Clark cell) and a receiver.

Alarms
To facilitate alarm management with different thresholds for each product being analyzed, up to 40 recipes may be programmed in which the operator enters the limit values of every parameter for each soft drink. The individual recipe is called up at beginning the of each work session. When the IB05 analyzer detects values that exceed those entered in the recipy being utilized, alarm messages are triggered, alerting the operator and allowing him/her to intervene in the process. An output contact allows to activate a remote acoustic or optical alarm.

Data transmission
The IB05 analyzer is equipped with analog and serial outputs. Analog outputs 4-20 mA are used for connection to a paper recorder in the laboratory or field, while the serial outputs are used for data transmission between the analyzer and remote repeater, for communication with the Maselli Brix and CO
2 controller, and with the MULTILAB IV remote control and data acquisition software installed on the PC located in the Quality Control Lab.
The serial outputs may also be used for continuous print-out of a variety of data or other information on a local printer.

Brix Controller
The Brix control is customized for the type of soft drink production plant in which it is installed. Normally, two different systems may be used:
a) Dosing using dosing pumps
b) Orifice regulation
In the first case, the controller drives a motor and regulates the position of the dosing pump head; in the second it controls the position of the flow regulation valves. The Brix controller can receive the parameters of the soft drink to be produced from either the IB05 analysis unit or the remote MULTILAB control unit located in the laboratory, always with the 40 programmable recipes system.

CO2 Controller

The CO2 controller can be made in two different systems:
a) injection CO2 controller
b) saturation CO2 controller
In the first case, a flow transmitter measures CO2 flow rate in the feed pipe and the controller keeps this constant using an electro-pneumatic translator that drives a pressure reducer. In the second, a pressure sensor located on the product tank detects CO2 pressure and the controller keeps this constant driving an electro-pneumatic translator that controls the pressure reducer. In both systems, the controller flow rate or pressure setpoint value is "cascade" modified by the IB05 that reads the CO2 value of the finished product.

Recorder or Printer
In order to collect the data read by the analysis units, either a
continuous-form analog recorder or serial printer can be installed in the field. The printer, driven by dedicated software, print out the results in graphic and numeric form.

Remote Display
To complete the BAS02 System, a display that shows the Brix and CO2 degree values as well as the alarm status is available. The remote display is useful when the measuring devices are located in positions not visible to the operator.

Remote Control and MULTILAB IV data acquisition software
The production line can be run from the laboratory using the MULTILAB IV remote control unit which, thanks to a two-way serial connection with the IB05 unit, functions as a remote terminal in the lab, allowing to monitor and modify all functions. The system can communicate with 8 different units located on various lines. The MULTILAB IV data acquisition section displays production data in graphic form, gives current values and alarm status for each line and creates job reports that can be printed out and consulted at a
later date using the standard programs in the MULTILAB IV or specific customer software.
